If I just think of a q&d solution: long exp10(int x) { long result = 10; while (--x) { result = result * 10; } return result; } I haven't tested this, but it can be something like this. (And I'm sure it's slow as hell for large values of x) Tomas lear_at_algonet.se wrote: >Hi, > >For an upcoming patch, I need some fixed- or floating-point math.
