Pow() and math.h [SOLVED]

I was trying to use pow() in my code yesterday, and it wouldn’t compile unless I included #include <math.h>. Can anyone else independently verify/confirm this? If confirmed, I can submit a pull request to update the docs.

Hi @wgbartley

That is right but it is already in the doc:

Note that in addition to functions outlined below all of the newlib math functions described at sourceware.org are also available for use by simply including the math.h header file thus:#include "math.h"


Ahh… I didn’t see that part. I just jumped straight to the function docs. I think I’ve used map() in the past without including math.h, so I never thought to check the introduction to the section. Thanks for pointing that out!
