creal, crealf - complex real functions SYNOPSIS
#include <complex.h> double creal(double complex z); float crealf(float complex z); long double creall(long double complex z); DESCRIPTION
These functions compute the real part of z. RETURN VALUE
These functions return the real part value. ERRORS
No errors are defined. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
For a variable z of type complex: z == creal(z) + cimag(z)*I RATIONALE
None. FUTURE DIRECTIONS
None. SEE ALSO
