Function std.complex.norm

Extracts the norm of a complex number.

T norm(T) (
  Complex!T z
) pure nothrow @nogc @safe;


z A complex number


The squared magnitude of z.


import std.math.operations : isClose;
import std.math.constants : PI;
writeln(norm(complex(3.0, 4.0))); // 25.0
writeln(norm(fromPolar(5.0, 0.0))); // 25.0
assert(isClose(norm(fromPolar(5.0L, PI / 6)), 25.0L));
assert(isClose(norm(fromPolar(5.0L, 13 * PI / 6)), 25.0L));
