What is an argument in an excel function

Arguments are the values that functions use to perform calculations. In spreadsheet programs such as Excel and Google Sheets, functions are just built-in formulas that carry out set calculations and most of these functions require data to be entered, either by the user or another source, in order to return a result.

What is the argument in an Excel function?

A function argument is a specific input to a function. For example, the VLOOKUP function takes four arguments as follows: =VLOOKUP (value, table, col_index, [range_lookup]) Note most arguments are required, but some are optional. In Excel, optional arguments are denoted with square brackets.

What are arguments in Excel explain giving example?

Most of the functions found in Excel require some input or information in order to calculate correctly. For example, to use the AVERAGE function, you need to give it a range of numbers to average. =AVERAGE(A1:A100) Any input you give to a function is called an argument.

What is the type argument in Excel?

The Excel TYPE function returns a numeric code representing “type” in 5 categories: number = 1, text = 2, logical = 4, error = 16, and array = 64. Use TYPE when the operation of a formula depends on the type of value in a particular cell.

What are the two kinds of arguments in Excel?

The types of arguments that are used in Excel are given below.

• Numeric data (=SUM(5,10))
• Text-string data (=UPPER(“siam”))
• Boolean values (=OR(1+1=2))
• Error Values (=ISERR(#VALUE!))
• Other functions (=DATE(YEAR(A2) + B2, MONTH(A2), DAY(A2)))

What are the 3 arguments of the IF function?

There are 3 parts (arguments) to the IF function:

• TEST something, such as the value in a cell.
• Specify what should happen if the test result is TRUE.
• Specify what should happen if the test result is FALSE.

How do you create an argument in Excel?

Follow these steps:

1. Click the cell with the existing function.
2. Click the Insert Function button. The Function Argument dialog box appears.
3. Add, edit, or delete arguments, as follows:
4. Click OK when you’re finished.

What is the argument of a story?

Argument Definition
An argument is the main statement of a poem, an essay, a short story, or a novel, which usually appears as an introduction, or a point on which the writer will develop his work in order to convince his readers. Literature does not merely entertain. It also intends to shape the outlook of readers.

What is an argument in parentheses?

1. For the initial line of a Sub or Function, you use parentheses to enclose the arguments (if any), e.g. Sub MySubroutine(a As Long, b As String) or. Function MyFunction(a As Long, B As String) As Long.

How many arguments can a function have in Excel?

The concept of additional optional arguments is expressed with ellipses, which appear at the end of the argument list when a function takes multiple optional arguments. The SUM function can actually accept up to 256 arguments total.

What are the 3 types of cell references in Excel?

Relative, Absolute and Mixed
A key element of a formula is the cell reference, and there are three types: Relative. Absolute. Mixed.

What is a syntax in Excel?

The syntax of a function in Excel or Google Sheets refers to the layout and order of the function and its arguments.All functions begin with the equal sign ( = ) followed by the function’s name such as IF, SUM, COUNT, or ROUND.

How do you access function arguments in Excel?

Keyboard shortcut fans might know that you can start typing a formula, like =VLOOKUP(, into a cell and then press Ctrl+A to open the Functions Argument for that function.

What are the 10 logical functions in Excel?

Excel logical functions – overview

Function	Description	Formula Example
AND	Returns TRUE if all of the arguments evaluate to TRUE.	=AND(A2>=10, B2<5)
OR	Returns TRUE if any argument evaluates to TRUE.	=OR(A2>=10, B2<5)
XOR	Returns a logical Exclusive Or of all arguments.	=XOR(A2>=10, B2<5)

How do you create a logical argument in Excel?

Use the IF function, one of the logical functions, to return one value if a condition is true and another value if it’s false. For example: =IF(A2>B2,”Over Budget”,”OK”) =IF(A2=B2,B4-A4,””)
Syntax.

Argument name	Description
value_if_false (optional)	The value that you want returned if the result of logical_test is FALSE.

How many arguments are required for the SUM function?

These values can be numbers, cell references, ranges, arrays, and constants, in any combination. SUM can handle up to 255 individual arguments. The SUM function takes multiple arguments in the form number1, number2, number3, etc. up to 255 total.

What is Vlookup in Excel?

VLOOKUP stands for ‘Vertical Lookup’. It is a function that makes Excel search for a certain value in a column (the so called ‘table array’), in order to return a value from a different column in the same row.

What does spill mean in Excel?

#SPILL errors are returned when a formula returns multiple results, and Excel cannot return the results to the grid.

What is the third argument in an IF statement in Excel?

The IF Function has 3 arguments: Logical test. This is where we can compare data or see if a condition is met. Value if true.

What does the rand function do?

RAND returns an evenly distributed random real number greater than or equal to 0 and less than 1. A new random real number is returned every time the worksheet is calculated. Note: As of Excel 2010, Excel uses the Mersenne Twister algorithm (MT19937) to generate random numbers.

What is argument explain with example?

For example, consider the argument that because bats can fly (premise=true), and all flying creatures are birds (premise=false), therefore bats are birds (conclusion=false). If we assume the premises are true, the conclusion follows necessarily, and it is a valid argument.

Arguments in Excel Functions are input values to an Excel Function. Most of the Excel Functions will take one or more arguments, will be used in the function programs as input data and return the outputs. For example, Trim Function will take a string as input (argument) and returned the output by removing the extra spaces from the string.

VBA Optional Arguments and Default Values

September 04, 2021

When creating your VBA subs and functions, you may come across a time where you want to have an optional parameter — something that the calling procedure doesn’t have to specify, but can if they like. You may also want to have that optional argument have a default value in case nothing is supplied. So how do we do this? It’s easier than you think.

Here’s an example of a function that takes a name, a salutation, and outputs a greeting:

Let’s make the salutation part optional:

All we did was add the Optional keyword at the beginning of the parameter definition.

So what happens if we don’t pass anything to it?

Since we didn’t specify a value for salutation , the default value for a string was used (which is a blank string).

Let’s now add a default value for salutation :

Now let’s re-run the function:

Great, it works as expected.

Here’s our full code sample so far:

List Optional Parameters at the End of the Procedure Definition

Optional parameters must be listed at the end of the procedure definition. This means that the procedure definition will have a set of required parameters, followed by a set of optional ones (or, you can have only optional parameters).

For example, say you have a procedure with 2 required parameters and 2 optional ones:

You cannot have the optional arguments in any position except the end of the definition. For example, this wouldn’t work:

Even though there is an optional argument at the end ( myOptionalArg2 ), there is an optional argument before a required one ( myOptionalArg1 is before required2 ) and that syntax is invalid.

Optional Arguments can be any Type Except a UDT

Optional parameters can be any type except a User Defined Type. If you specify a user defined type, when the code compiles, you will receive this error:

Detecting a Missing Parameter

If you want to know if a parameter was passed in by the caller or not, you can use the IsMissing function. This will return True if the parameter was not supplied to the procedure, but only under certain conditions:

1. There cannot be a default value for the parameter in the procedure definition.
2. The type for the parameter must be Variant . Simple types like Long , Boolean , String will always have IsMissing return False , this is because for simple types, a default value is already supplied (for Long , it’s 0 , Boolean is False , String is «» ).

Because we defined our salutation parameter as a string and we gave it a default value, our current code will not work:

In order for the IsMissing function to return True , we need to remove the default value and change the type to Variant :

Now, salutation is an undefined Variant object and IsMissing(salutation) will return True . However, because it’s missing, VBA doesn’t have anything to refer to when we try to access it, so when we try to return salutation & «, » & name & «!» , it will throw an error.

One way to fix this is to avoid using the salutation variable when it’s not supplied:

Another way to fix it would be to supply a default value later in the code:

For our example, it would be better to change salutation to be a String and supply a default value for it. However, you may have a specific scenario where you need to know if a parameter was intentionally left out, in which case, you can use the IsMissing function as we did above.

How do I supply one optional parameter out of two?

If you have multiple optional parameters and only want to specify some of them, you can do so using a feature called named arguments. We’ll have another blog post on this topic in more depth, but for now, we’ll explain its usage briefly.

To use named arguments, when calling the procedure, you specify the variable you want to supply a value to by using a colon followed by an equal sign in this format:

Here’s a quick example:

Here, we have two arguments: salutationStart and salutationEnd . We made the type Variant and left out a default value, allowing us to make use of the IsMissing function.

When we call CreateGreeting with just the name and salutationEnd :

We are telling VBA that the second parameter we listed is specifically for the salutationEnd argument in the procedure definition of CreateGreeting . This means that the salutationStart variable is not supplied and when we call IsMissing(salutationStart) it will return True .

Again, we’ll dive into named arguments in a later post, but for now, this is how you can specify optional arguments when you don’t want to (or can’t) supply them all.

Wow, you read the whole article! You know, people who make it this far are true learners. And clearly, you value learning. Would you like to learn more about Excel? Please consider supporting me by buying me a coffee (it takes a lot of coffee to write these articles!).

Understanding named arguments and optional arguments

When you call a Sub or Function procedure, you can supply arguments positionally, in the order that they appear in the procedure’s definition, or you can supply the arguments by name without regard to position.

For example, the following Sub procedure takes three arguments.

You can call this procedure by supplying its arguments in the correct position, each delimited by a comma, as shown in the following example.

You can also call this procedure by supplying named arguments, delimiting each with a comma.

A named argument consists of an argument name followed by a colon and an equal sign (:=), followed by the argument value.

Named arguments are especially useful when you are calling a procedure that has optional arguments. If you use named arguments, you don’t have to include commas to denote missing positional arguments. Using named arguments makes it easier to keep track of which arguments you passed and which you omitted.

Optional arguments are preceded by the Optional keyword in the procedure definition. You can also specify a default value for the optional argument in the procedure definition. For example:

When you call a procedure with an optional argument, you can choose whether or not to specify the optional argument. If you don’t specify the optional argument, the default value, if any, is used. If no default value is specified, the argument would be for any variable of the specified type.

The following procedure includes two optional arguments, the varRegion and varCountry variables. The IsMissing function determines whether an optional Variant argument has been passed to the procedure.

You can call this procedure by using named arguments as shown in the following example.

A function with an optional argument

Many Excel built-in worksheet functions use optional arguments. An example is the LEFT function, which returns characters from the left side of a string. Its official syntax follows:

The first argument is required, but the second is optional. If you omit the optional argument, Excel assumes a value of 1. Therefore, the following formulas return the same result:

The custom functions you develop in VBA also can have optional arguments. You specify an optional argument by preceding the argument’s name with the keyword Optional, followed by an equal sign and the default value. If the optional argument is missing, the code uses the default value.

Debugging custom functions

Debugging a Function procedure can be a bit more challenging than debugging a Sub procedure. If you develop a function for use in worksheet formulas, you find that an error in the Function procedure simply results in an error display in the formula cell (usually #VALUE!). In other words, you don’t receive the normal runtime error message that helps you locate the offending statement.

You can choose among three methods for debugging custom functions:

I Place MsgBox functions at strategic locations to monitor the value of specific variables. Fortunately, message boxes in Function procedures pop up when you execute the procedure. Make sure that only one formula in the worksheet uses your function, or the message boxes appear for each formula that’s evaluated — which could get very annoying.

I Test the procedure by calling it from a Sub procedure. Run-time errors appear normally in a pop-up window, and you can either correct the problem (if you know it) or jump right into the debugger.

I Set a breakpoint in the function and then use the Excel debugger to step through the function. You can then access all of the usual debugging tools. Refer to Chapter 13 to find out about the debugger.
