Thanks, Mirek, always worth hearing your opinion on the subject. Haven't done a lot of research into floating point because I'm not a heavy math guy so much of the math here:

https://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.h tml

was beyond me. Also watched this video about posits and found the subject interesting.

Perhaps I'm just leery about the entire subject because other devs have warned me off doing it. I'll look more into BCD, the last I heard about that was in an x86 assembly class relating to hardware instructions like AAA and packed decimal we never went into. I'm assuming there are SIMD instructions for the same concept.
