I want to round in addition with 2 decimal places some numbers
For example the number 68.225 → 68.23

I have used this function:
Math.Round(double.Parse(“68.225”), 2, MidpointRounding.AwayFromZero)
The result is 68.22 and not 68.23.
How exactly works MidpointRounding.AwayFromZero because I cannot get it…?

XX.225 with a round of 2 digits will come in this case to

if the next digit is 5, which is the midpoint between two possible results, and all remaining digits are zero or there are no remaining digits, the nearest number is ambiguous

so there is no more close / more far and we see the cutoff / round down .225 → .22

Yes but this is the idea to use AwayFromZero to take the decision in which direction will go, to .22 or to .23

Math.Round(68.225, 2) is the same thing with Math.Round(68.225, 2, MidpointRounding.AwayFromZero) and is not ok in my opinion because when I specify AwayFromZero I expect to round in addition.

Perhaps, I still don’t get it but how can I obtain .23 starting with .225?

I will test this one but there is a solution to obtain directly a Double without conversion from that string to Double (Double.Parse(68.225.ToString(“F2”))) ?

I will set as solution your last comment.
I have one more question.
From what I have read I understand that the pattern .XX5 can generate this problem but why cases like .215 or .235 are working as expected?
