1-3) Computes the complex absolute value (also known as norm, modulus, or magnitude) of
z.4) Type-generic macro: if
z has type long double complex or long double imaginary, cabsl is called. If z has type float complex or float imaginary, cabsf is called. If z has type double complex or double imaginary, cabs is called. For real and integer types, the corresponding version of fabs is called.Parameters
| z | - | complex argument |
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))
