ratio< Num, Denom > Struct Template Reference

The typename template provides compile-time rational arithmetic support. Each instantiation of this template exactly represents any finite rational number as long as its numerator Num and denominator Denom are representable as compile-time constants of type intmax_t. More...

Detailed Description

template<intmax_t Num, intmax_t Denom = 1>
struct etl::ratio< Num, Denom >

The typename template provides compile-time rational arithmetic support. Each instantiation of this template exactly represents any finite rational number as long as its numerator Num and denominator Denom are representable as compile-time constants of type intmax_t.
