Hello friends,
Good Evening
I want to covert the decimal values to the nearest decimal number i.e
Suppose my value is

87.6408
then O/P should be either 60 if below 5 and 70 above 5
87.60 or 87.70
Any help will be appreciated. I have tried
noo = Math.Round(noo, 2,MidpointRounding.ToEven);and also
noo = Math.Round(noo, 2,MidpointRounding.AwayFromZero);This is working but not as I want. Please help.Thank You

Solution 2

Convert the decimal ToString("#.##")
this leads to "12345.67"
Read the last char from string and decide if it should be down or up (60 or 70)

Solution 4

The way you describe your problem already holds the answer. You want to do rounding to 87.60 or 87.70 for example. You do rounding to two decimal values but actually you want one decimal, meaning you would like to round to 87.6 or 87.7 (the extra zero would only be for display and has no meaning for the number itself)

Good luck!

Ya that's right but I am converting this value in word format so while printing i need to Print .60 or .70 to sixty or seventy paise.Please help me

Just use this to format it for display: String.Format("{0:0.00}", 87.6); -> 87.60

Solution 5

You may try

C#

string numString = string.Format("{0:####0.00}",Math.Round(num,2, MidpointRounding.AwayFromZero));

0.00 in the format string ensures that .6 is printed as 0.60.

Then put Math.Round(num,1,MidpointRounding.AwayFromZero), the 112.36 will be rounded to 112.4 and printed as 112.40
