Hi ,

  I am using the CCES to program a custom module for Sigmastudio.I want to use the math functions in the "<math.h>",such as "fabsf".I have declare as followed: "include<math.h> \\ float fabsf(float)".When I envoke the function,it shows :"warning:the function fabsf declared implicitly".Wat's wrong with it?
