Rounding values up or down in C#

Question

Hey all,

I've created a game which gives a score at the end of the game, but the problem is that this score is sometimes a number with a lot of digits after the decimal point (like 87.124563563566). How would I go about rounding up or down the value so that I could have something like 87.12?

Thanks!

Answer 1

Try using Math.Round. Its various overloads allow you to specify how many digits you want and also which way you want it to round the number.

Answer 2

double test2 = 87.2345524523452;
double test3 = Math.Round(test2, 2);

Answer 3

Use Math.Ceiling(87.124563563566) or Math.Floor(87.124563563566) for always rounding up or rounding down. I believe this goes to the nearest whole number.
