Hi,

 

I have a question regarding using functions like Tan inverse CodeWarrior. I am using CodeWarrior version 10.6.4 and the micro controller is part of the MC9S12ZVC family and I am using a USB multilink universal debugger to communicate. 

 

Is there a function I can use for getting the Tan inverse of a number ? I tried using atan and atanf functions but neither of them worked. Inclusion of math.h or GFLIB.h did not help. Is there a way this can be done ? 

 

Sincerely,

Mahendra
