Absolute value round
I'm working on a project right now assigned by my professor. It involves a DateTime object that takes gregorian calendar and converts it to Julian Date, and vice versa. Right now when I give it a certain hour/minute/second it's not giving me exactly the right value. So my professor said to create a function that compares the number I calculate, and the number it should be and if it's really close, for example: 0.1 compared to 0.09999999992, then to return true that they are the same number. He said to use a library, that would know absolute value, but I forget the name of the library he said, and I can't find it.
