Question

Round Double to 2 decimal places in C# for math

Asked by: Pwit

Hi all,

Is there a way to round a Double number such as 12.4556 to something like 12.46?  I found ways online that can round the Double number down, but through that way it converted the number to a String.  I would like to use the number for math after rounding it to 2 decimal places also.  Thanks.

Does "banker's rounding" which is considered more accurrate than 5up/4down rounding.

Super Simple.

How about Math.Round(12.4556, 2)?

 

by: ddayx10Posted on 2009-08-28 at 10:10:34ID: 25209653

LOL the link is for Math.Round on msdn. I thought it more important to give the specifics because it can be confusing how the rounding is managed unless you RTFM.

Hi guys,

Thanks for all the quick responses.  Math.Round with the midpoint rounding did the trick! Thanks again for all your help :)
