Hi,
I'm translating a timer that returns the date in seconds from a consistent start time 70 years ago. It creates a 10 digit number. I tack on a few more digits for my product key manipulation.
Problem is, the values I get back are inconsistent. I understand that an integer has a range limit below my number, but even when I convert everything to floats, I run into problems after 12 digits. I've duplicated the problem in this simple COFFEE expression.
Any ideas?
Thanks,

Do it as a string. Numbers in computer format can't start with a '0' (except for number smaller than 1 (0.xxxx) in floating point).
