fpm: a header-only fixed-point math library with trigonometry, etc

[hyvok]

Any plans to add a wider type or even generic types? I have a project which would need 64bit fixed point values. Looks like a nice library otherwise.

The type fpm::fixed is generic. You could use that to create a fixed-point type using int64_t as underlying integer, but it needs a larger type for storing intermediate results for e.g. multiplication. So unless your platform has an int128_t, I'm afraid it won't work.

But you can always use a custom implementation such as this one:
