Hi friends,

I am using VS 2005,C#,asp.net.
I am using Math.round function to round to 2 decimal points.
Math.round(200.925,2) =200.92
Not rounding to 200.93.
But Math.round(200.935,2) =200.94
Math.round(200.945,2) =200.95
What is the reason for not rounding of 200.925

Regards,
george n

From the documentation
http://msdn.microsoft.com/en-us/library/3s2d3xkk.aspx[^]

If the fractional component of d is halfway between two integers, one of which is even and the other odd, the even number is returned. Note that this method returns a Decimal instead of an integral type

Now you state that Math.round(200.945,2) = 200.95 which would then be wrong according to the documentation. On my system Math.round(200.945,2) = 200.94
