i am using RVDK 2.1. I want to calculate the arcsin() of some value. I thought on using the math.h, but i could not find it. Is it supposed to be there or is the standard libray (including math.h) not fully implemented? regards, Erwin
math.h file is available with the RVDK compiler stander library under the following directory: C:\Program Files\ARM\RVCT\Data\2.1\498\include\windows Regards, Hichem
