Rational

A compile-time rational number.

If you explicitely specify the denominator, be sure to use an *unsigned* integer literal (e.g. 2u) – even though the template accepts only unsigned integers anyway, this seems to make a difference.

Note: This was tailored to the specific needs of the units library, and isn't optimized at all.

@safe

template Rational (

int n

uint d = 1u

) {

@safe

enum gcd_;

alias Rational = Rational!(n / cast(int)gcd_, d / gcd_);

struct Rational;
