cabs - calculate absolute value of complex number (BS2000)

Syntax	#include <math.h> double cabs(__complex z);
Description	cabs() calculates the absolute value of a complex number z. struct (__complex z) is a complex number z with real part x and imaginary part y. __complex is a type predefined in the header math.h: #typdef struct{double x, y;} __complex
Return val.	Absolute value of the complex number z if successful. If an overflow occurs, the program aborts (signal SIGFPE).
