previously we used the bigfloat abstraction to do all
compile-time float math. but runtime code and comptime code
are supposed to get the same result. so now if you add a
f32 to a f32 at compile time it does it with f32 math
instead of the bigfloat. float literals still get the
bigfloat math.
closes#424
This does not fix the underlying issue in pow at this stage, but we may
be able to narrow down the cause after adding tests for specific edge
cases in functions.
This covers the majority of the functions as covered by the C99
specification for a math library.
Code is adapted primarily from musl libc, with the pow and standard
trigonometric functions adapted from the Go stdlib.
Changes:
- Remove assert expose in index and import as needed.
- Add float log function and merge with existing base 2 integer
implementation.
