Sequential Serial Numbers was created by biqut2
I recently had a job that required sequential serial numbers on each part. I made a half hearted attempt to find an existing solution ready to run and came up empty handed. I did come across andypugh's work which was close but not quite what I needed. Basing my solution of his work I came up with the following solution for my needs and wanted to share it in case it could be of use to anyone else. I know its not the most efficient or well polished but it works.

It might have been simpler to just store a single decimal number and increment that.
Then iterate through it one digit at a time. Starting with the rightmost digit you can get that with the MOD function. Then divide (a copy of) the number by 10, and repeat the MOD operation for as many digits as you need.
Parameters are saved as type double, so around 15 digits of precision.
(I imagine that you did it the way that you did because you were concerned about rounding errors and finite float precision?)

I did it that way for two reasons: Firstly, yes I've had bad encounters with rounding errors in the past and try to avoid that at all cost, Secondly, I threw this together in between running other jobs and was a bit scatter brained and overwhelmed at the time.

I stopped as I was writing and started to do it the other way but I had already started down this route and just needed it to work.

As a side note, I did use ASCII codes for the numbers with the intent of coming back and including the alphabet, making it a base 36 number system.

EDIT: For what its worth, I've never had rounding issues with LinuxCNC. I do run a Fanuc though where sometimes 1 - 1 does not equal 0!
