Die Vorlage alias std::ratio_divide bezeichnet das Ergebnis der Division zweier exakten rationalen Fraktionen von den std::ratio Fällen vertreten R1 und R2. Das Ergebnis eine Instanz std::ratiostd::ratio<Num, Denom> wo Num == R1::num* R2::den und Denom == R1::den* R2::num .

Original:

The template alias std::ratio_divide denotes the result of dividing two exact rational fractions represented by the std::ratio instances R1 and R2. The result a std::ratio instance std::ratio<Num, Denom> where Num == R1::num* R2::den and Denom == R1::den* R2::num.

Beispiel

#include <iostream>#include <ratio>   int main(){typedefstd::ratio<2, 3> two_third;typedefstd::ratio<1, 6> one_sixth;typedef std::ratio_divide<two_third, one_sixth> r;std::cout<<"2/3 / 1/6 = "<< r::num<<'/'<< r::den<<'\n';}

Output:

2/3 / 1/6 = 4/1
