## Fixes #111 > The modulo operator on this calculator gives the result that is different to the most used calculators. The current `modrate` function is the equivalent of rem(...)/remainder(...), not mod(...)/modulo(...) available in some popular Math apps. ### Description of the changes: - rename `modrate` in `remrate` to be more accurate. - add `modrate`, calculating modulo similarly to Matlab, Bing, Google calculator, Maxima, Wolfram Alpha and Microsoft Excel - Add `RationalMath::Mod` using `modrate` as an alternative to `Rational::operator%` using `remrate` - Add a helper `SIGN` to retrieve the sign of a `Rational`. - modify `CalcEngine` to use `modrate` in Normal and Scientific mode and `remrate` in Programmer mode. ### How changes were validated: - manually and unit tests added
