Christopher Gauntt, Cordega Solutions

Converts a text based Get (UUID) to a 41 digit number

Sample Input:
HexUUIDToNum_cf ("DBB8EE4A-01F8-5B41-B598-4663A715E569")

HexUUIDToNum_cf ("00000000-0000-0000-0000-000000000000")

Sample Output:



 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


This function concatenates the five segments of a Get (UUID) text-based hexadecimal, converts it into a fixed length decimal and then adds a preset value to make sure the result is a uniform 41 digit number that still functions as a UUID, with no leading or trailing zeros.

This is intentional for two reason:
1. the forced 1 at the end will prevent a scientific notation from returning if there happen to be too many zeros in a row at the end.
2. the forced 1 at the beginning will guarantee a fixed length value, which may be important when switching a system over from a serial number based uid to a numeric uuid

Feedback welcome.
