View Source Scenic.Math (Scenic v0.11.2)

Helper functions that support Scenic mathematical operations.

The math functions are fairly straightforward. When performance is needed some have been broken out into a NIF.

The NIF functions are currently written for compatibility over top speed and as such, there is an opportunity to further improve them by calling out to CPU-specific vector instructions in the future.
