[ string->isdigit ]


[String->IsDigit] checks whether a specified character within the string object is a digit. If the parameter specifying the position of the character to be examined is omitted, then the default position 1 (or first character in the string object) is examined. The tag returns True if the character is a digit or False otherwise.
