IsNumeric
The IsNumeric function, Boolean, returns true if the value passatole as a parameter is numeric and false if not.
The syntax is as follows:
document.write (IsNumeric (5))Returns True
document.write (IsNumeric ("Luke"))
Returns False.
The "IsNumeric" is frequently used to verify that a value is numeric or not, then perform different routines depending on the result, as in the following:
Dim value
value = "Luke"
If IsNumeric (Value) = False Then
document.write ('E' number ')
Else
document.write ("Not a number")
End If
Returns "is not a number."
