Mallari --

This appears to be the result of converting decimal values which we read into binary format for calculation and conversion back. All computer languages which use a floating point format will exhibit this kind of behavior in such calculations.

A couple possible solutions:

Use the ROUND() function to the desired number of places (which can be tedious),

Use the currency data format if you are interested in 2 or 4 decimal digits of accuracy. These calculations undergo an automatic rounding in VFP.

Try the addition but prefix a $ sign -- or other currency marker. I found that the sum of the values equaled the values summed.
