My own unofficial Asymptote module with some useful functions:

Documentation

This function is actually part of newer versions of Asymptote, but is not supported in 2.32 so I decided to make it. What it does is it takes a string and splits it into individual characters.

Returns the number of digits in the given integer.

Converts strings into integers.
