Replaces the free-standing functions in f32, &c.

The free-standing functions in f32, f64, i8, i16, i32, i64, u8, u16,
u32, u64, float, int, and uint are replaced with generic functions in
num instead.

If you were previously using any of those functions, just replace them
with the corresponding function with the same name in num.

Note: If you were using a function that corresponds to an operator, use
the operator instead.
