struct std::ratio< _Num, _Den >"Provides compile-time rational arithmetic\&. 

This class template represents any finite rational number with a numerator and denominator representable by compile-time constants of type intmax_t\&. The ratio is simplified when instantiated\&.

For example: 
.PP
.nf
std::ratio<7,\-21>::num == \-1;
std::ratio<7,\-21>::den == 3;
