how do you use mod and exponents in c++? *mod as in modular math. |

mod is % and exponent is the function float pow(float num,float exp) in <math> avoid pow whenever necessary it can be very very slow (i.e use x*x*x over pow(x,3)) |

considering the purpose of the site and the lack of any advertisement or help to fund the site, i think cppreference is pretty damned nice to pay for its domain for the content it gives. also try cprogramming.com and codenewbie.com |
