This is the mathematically correct way. If you do want to round based on the 2nd decimal digit and ignore the 1st... I fail to see any logic in that.Mathematically it's the correct way to round, but there may be a requirement, say in engineering, where there are "tolerence levels" on certain things. In which case it's perfectly logical.
That being the case, Frank's solution is just what is required...
