## Notes

- Sin, cos, tan, pow, log, and abs (particularly pow and log) are extremely slow. Do not use them in script blocks that get executed every frame.
- This function is new in the GECK, and was not available in the TES4 Construction Set. However, it was available through the OBSE script extender.
