Please don't misunderstand this work, it is 'just' fast or even up to 3.5 times faster than the original routines! Indeed, it is way more! The routines give the user reliable results, too! That is very important for calculations. Further, they maintain the jump addresses from the original routines from Atari. Therefore, no trouble, just have fun and enjoy.

The routines make use of the [CORDIC algorithm|https://en.wikipedia.org/wiki/CORDIC] please see at the bottom for an example in Microsoft Excel.
