rounding to a specific place?
when I have cin >> dprice; get a double value and I type in 8.88, it gets immediately stored as 8.8800000000000008. Now the real questions about this would be like why does it do that, why don't they fix that, and why do people still use C++ when it does stuff like that?
But my question for the time being is, how can I round that value off to one less place to get rid of the extra value that gets tacked on? Math.h's ceil rounds it up to 9 and floor drops it to 8 and it doesn't seem to take any parameters for the amount of decimal places I want so is there another common library that has a round function or any other way to fix it other than rounding?
oh and btw, MSND says the C++ version of math.h has a round function that does just that but the compiler says it doesn't.
