Question

I have a report field that can contain different types of data, therefore I need to do my rounding and formatting using functions.

In one case, I have a decimal(9,2) value storing hours that I need to display as minutes with zero decimal places.

Round(foo*60, 0), where foo = .01 (which is 0.6 when multiplied by 60), is outputting 1 like I would expect.

Round(foo*60, 0), where foo = .21 (which is 12.6 when multiplied by 60), is outputting 12 instead of 13.

Why? How can I get it to consistently use standard 4/5 rounding?

Take a look at this other stackoverflow question:

SQL Server Reporting Services Round() function

You are seeing Round to Even logic rather than mid point rounding.

This Wikipedia article has all the details about rounding:
