If you are, and sscanf() isn't an option, the algorithm for processing a number from text isn't terribly complicated.

Yes, I wrote (actually, stole from the intarwebs ) an equivalent of 'atoff' and it works a treat.

If you're not processing user text input, I suggest preprocessing your data into some binary number format to make things easier on the Playdate end.

I'm processing .obj files exported from Blender (obj format details). It was much easier to just write 'atoff' than create an external pre-processing utility to convert .obj to binary.
