Function std.complex.sqAbs
T sqAbs(T)
(
Complex!T z
) pure nothrow @nogc @safe;
T sqAbs(T)
(
const T x
) pure nothrow @nogc @safe
if (isFloatingPoint!T);
Parameters
Name | Description |
---|---|
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 .operations : isClose;
writeln(sqAbs(complex(0.0))); // 0.0
writeln(sqAbs(complex(1.0))); // 1.0
writeln(sqAbs(complex(0.0, 1.0))); // 1.0
assert(isClose(sqAbs(complex(1.0L, -2.0L)), 5.0L));
assert(isClose(sqAbs(complex(-3.0L, 1.0L)), 10.0L));
assert(isClose(sqAbs(complex(1.0f,-1.0f)), 2.0f));
