// Fast fixed-dividend divider generator in C++11
// by Davin McCall <davmac@davmac.org>
//
// Division is a relatively very slow operation even on modern processors. This
// template (ffdiv) produces a divider that will divide any number up to a fixed
// limit by a fixed dividend, using a multiplication and shift operation. I

//
// Compile with (for eg) "gcc -std=c++11".
