Function float_to_int_inner

fn float_to_int_inner<F, I, FnFoo, FnOob>(
    fbits: F::Int,
    map_inbounds: FnFoo,
    out_of_bounds: FnOob,
) -> I
where
    F: Float,
    I: Int,
    FnFoo: FnOnce(I) -> I,
    FnOob: FnOnce() -> I,
    I::UnsignedInt: Int,
    F::Int: CastInto<I::UnsignedInt> + CastFrom<u32>,
    u32: CastFrom<F::Int>,

Float to int conversions, generic for both signed and unsigned.

Parameters:

• fbits: abg(f) bitcasted to an integer.
• map_inbounds: apply this transformation to integers that are within range (add the sign back).
• out_of_bounds: return value when out of range for I.
