[jemminger]

is there a reason why

Round(10.25, 1)

results in 10.2 instead of 10.3???

Yes, as far as I know, there's a bug in Round method that leads to round bad the "5" digit to the inferior rather than superior. Water is not bad as long as it stays out human body ;-)

ok, i found some documentation that this is actually correct behavior according to the IEEE 754 standard for binary floating-point arithmetic...

standard or not, it's still wrong, or else every math teacher on the planet is teaching garbage when they say to round UP >=5, round DOWN < 5!!

here's a rounding lesson:

After the war in Irak between Saddam and W, will we soon see a war on the net between programers and math teachers ???
