@CharlesMar 31.2005 — #Contrary to what one might assume, computers are simply bad at math. But if you round everyting off to two or three decimal places, things usually work out alright.
@KorMar 31.2005 — #Computers are not good at [b]decimal[/b] math operations, as they convert first to binary, than calculate, than reconvert to decimal. Some floated numbers are not to be exactly converted into binary, thus small approximate round occures. Sometimes those small rounds added and the result is bizzare, from a decimal point of view.
