Struct fraction

struct fraction base

struct fraction { … }

Exact rational number represented as a numerator/denominator pair.

Always stored in normalized form: the denominator is positive and the numerator and denominator are coprime.

constructor fraction(i64, i64) 

fraction(i64 num = 0, i64 den = 1) noexcept

Construct a fraction from a numerator and denominator.

Parameters
num Numerator (defaults to 0).
den Denominator (defaults to 1); the result is normalized.

Fully qualified name: kfr::fraction::fraction(i64, i64)

Declared at base/fraction.hpp:44

function normalize() 

void normalize() noexcept

Reduce the fraction to lowest terms and enforce a positive denominator.

Fully qualified name: kfr::fraction::normalize()

Declared at base/fraction.hpp:49

variable numerator 

i64 numerator

Numerator of the fraction.

Fully qualified name: kfr::fraction::numerator

Declared at base/fraction.hpp:62

variable denominator
