NAME creal, crealf, creall - get real part of a complex number CONTENTS Synopsis Description Note SYNOPSIS #include <complex.h> "double creal(double complex "z); "float crealf(float double complex "z); "long double creall(long double complex "z); DESCRIPTION The creal() function returns the real part of the complex number z. One has z = creal(z) + I*cimag(z). NOTE The gcc supports also __real__. That is a GNU extension. "CONFORMING TO" C99 "SEE ALSO" cabs(3), cimag(3), complex(5)
