Function std.complex.sqAbs

Prototypes

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

T sqAbs(T)(
  T x
) pure nothrow @nogc @safe
if (isFloatingPoint!T);

Parameters

NameDescription
z A complex number.
x A real number.

Returns

The squared modulus of z. For genericity, if called on a real number, returns its square.

Example

import std.math;
assert (sqAbs(complex(0.0)) == 0.0);
assert (sqAbs(complex(1.0)) == 1.0);
assert (sqAbs(complex(0.0, 1.0)) == 1.0);
assert (approxEqual(sqAbs(complex(1.0L, -2.0L)), 5.0L));
assert (approxEqual(sqAbs(complex(-3.0L, 1.0L)), 10.0L));
assert (approxEqual(sqAbs(complex(1.0f,-1.0f)), 2.0f));
