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))
