Thank you for the clarification. To force float type in this case I use now:
ROUND(value, 2) + 0.0

This is correct in general. Most base-10 decimals cannot be represented exactly in IEEE floats. For example, the value 1.23 cannot be expressed as a 64-bit float. If you try, the machine will used the closest value it can store which is:
1.229999999999999982236431605997495353221893310546875
On the other hand, if the second argument to the round() function is zero (or is omitted) then the result will be an integer. And I wonder if it doesn't make sense in that case to return an integer value? -- D. Richard Hipp <[EMAIL PROTECTED]>
