In C++, do you know any function that given a real number x, gives us integers numerator and denominator? have a real x, and I'd like to know how it's written as a fraction. That is, I have the value for x, and I want to know the denominator d and the numerator n such as x = n/d.If you know a C++ library that has a function that gives me such integers, thanks.And sorry if my English isn't good xD
