Why would it round up? To 3 decimal places it is closer to 0.795

i know it does that already but the rest of calculations depends on the value being 0.796

ceil( 0.7954 * 1000 ) / 1000
It should also be noted though that many seemingly 'round' decimal numbers cannot be perfectly represented in floating point so that you likely will not have precisely 0.796 as your final answer.
