Syntax
IsNumeric(expression)


The expression argument can be any expression.

Remarks
IsNumeric returns True if the entire expression is recognized as a number; otherwise, it returns False. IsNumeric returns False if expression is a date expression.

The following example uses the IsNumeric function to determine whether a variable can be evaluated as a number:

Dim MyVar, MyCheck
MyVar = 53 ' Assign a value.
MyCheck = IsNumeric(MyVar) ' Returns True.
MyVar = "459.95" ' Assign a value.
MyCheck = IsNumeric(MyVar) ' Returns True.
MyVar = "45 Help" ' Assign a value.
MyCheck = IsNumeric(MyVar) ' Returns False.
