complex

fnauto complex(R)(const R re) if (is(R : double)) @safe pure nothrow @nogc

Helper function that returns a complex number with the specified real and imaginary parts.

Parameters

`R`	(template parameter) type of real part of complex number
`I`	(template parameter) type of imaginary part of complex number
`re`	real part of complex number to be constructed
`im`	(optional) imaginary part of complex number, 0 if omitted.

Returns

Complex instance with real and imaginary parts set

to the values provided as input. If neither re nor im are floating-point numbers, the return type will be Complex!double. Otherwise, the return type is deduced using std.traits.CommonType!(R, I).

fnauto complex(R, I)(const R re, const I im) if (is(R : double) && is(I : double)) @safe pure nothrow @nogc
