"WebDec 25, 2012 · On the fixed side you could bit shift instead of dividing by 100 (would have to convert to base 2 instead of base 10). So down to 10 clocks on the fixed side maybe, that one is iffy. Don't think you can do the bit shifting on the floating point since the exponents are all base 10. – Ryan Brown Dec 25, 2012 at 7:21 Add a comment 2 Answers Sorted by: " - Fixed point e floating point
