ABL electronic PIC12 Benutzerhandbuch

mikroC provides a set of standard ANSI C library functions for floating point
math handling.

Note: Functions have been implemented according to the ANSI C standard, but
certain functions have been modified in order to facilitate PIC programming.

acos(double x);

Function returns the arc cosine of parameter 

x

; that is, the value whose cosine is 

x

.

Input parameter 

x

must be between -1 and 1 (inclusive). The return value is in radians,

between 0 and pi (inclusive).
