Description

Returns True or False depending on whether the input string contains only numeric characters or currency format symbols. If this function returns True then you can safely use a Conversion function on it to turn it into a numeric data type.

This function allows for currency symbols defined within the computers regional settings.

Refer IsDigit for a function that checks only the first character to see if it is a digit. Refer to IsNumber for a function that checks if the string contains only numbers without currency formatting.
