conj(3) Library Functions Manual conj(3)
conj, conjf, conjl - calculate the complex conjugate
Math library (libm, -lm)
#include <complex.h> double complex conj(double complex z); float complex conjf(float complex z); long double complex conjl(long double complex z);
These functions return the complex conjugate value of z. That is the value obtained by changing the sign of the imaginary part. One has: cabs(z) = csqrt(z * conj(z))
