(synopsis "Faster integer division and modulus operations")
(description "Strength_reduce implements integer division and modulo via
@dfn{arithmetic strength reduction}. Modern processors can do multiplication
and shifts much faster than division, and arithmetic strength reduction is an
algorithm to transform divisions into multiplications and shifts. Compilers
already perform this optimization for divisors that are known at compile time;
this library enables this optimization for divisors that are only known at
runtime.")
