cabsf, cabs, cabsl

Parameters

Return value

If no errors occur, returns the absolute value (norm, magnitude) of z.

Errors and special cases are handled as if the function is implemented as hypot ( creal (z), cimag (z) )

Example

#include <stdio.h>
#include <complex.h>
 
int main(void)
{
    double complex z = 1.0 + 1.0*I;
    printf("%.1f%+.1fi cartesian is rho=%f theta=%f polar\n",
           creal(z), cimag(z), cabs(z), carg(z));
}

1.0+1.0i cartesian is rho=1.414214 theta=0.785398 polar
