将小数舍入到c＃中的两位小数

Question

I want to round 54.5345 to 54.54 that is if I have a third decimal place then i want to add 1 to the 2nd decimal place.

I have tried using math.round but it always rounds down if the third decimal is less than 5

Answer 1

try:

d = Math.Ceiling(d * 100) / 100;

where d is your decimal.

Answer 2

I think you should try this:

      double a = Math.Round(-57.5345, 2); 

This works for negative numbers too.

The way you are rounding off is not correct.
