Syntax
result = IsNumeric( arg )

Parameters
arg		Variable, value, or object whose data type is being investigated.

Return Value
Result	Boolean	True if arg is numeric; False otherwise.

Notes

If the value passed to IsNumeric is a String that contains the string version of a number, then IsNumeric returns True. For example,

IsNumeric("3.1416")

returns True.

One usage of IsNumeric is to determine whether the user entered a string that can be converted to a number. For example,

IsNumeric( "1234.65e+10" ) //returns True
IsNumeric( "567e-10.5" ) //returns False
