# cabsf, cabs, cabsl

From cppreference.com
< c‎ | numeric‎ | complex

Defined in header `<complex.h>` |  |
float cabsf( float complex z ); |  | (since C99)
double cabs( double complex z ); |  | (since C99)
long double cabsl( long double complex z ); |  | (since C99)

Computes the complex absolute value of `z`.

### [edit] Parameters

z | - | complex argument

### [edit] Return value

The complex absolute value of `z`.

### [edit] Example

Run this code

    #include <stdio.h>
    #include <complex.h>

    int main(void)
    {
        double x = cabs(1.0 + 2.0*I);
        printf("%f\n", x);

        return 0;
    }

Output:

    2.236068
