Function saturating_scale

pub fn saturating_scale(lo: i32, hi: i32, shift: u32) -> i32

Combine high and low i32 into a single downscaled i32, saturating monotonically.

Args: lo: LSB i32 to scale down by shift and range-extend with hi hi: MSB i32 to scale up and extend lo with. Output will be clipped if hi exceeds the output i32 range. shift: Downscale lo by that many bits. Values from 1 to 32 inclusive are valid.
