I just tried it and I think you have probably discovered a bug. I'm guessing it has to do with the fact that your second example has 4 more significant digits in the first operand and this causes the underlying software to add greater precision to its arithmetic algorithm...and somewhere there's a little bug in the conversion.

Notice that if you don't round, VFP produces a different number of significant digits in the console result. Also, I noticed that VFP puts the results of the rounded versions in different places on the screen. To me, this is all an indication that some threshold is being crossed in terms of the size of the internal representations of the operands and results, and there's a problem with the rounding function (my guess....the step in the rounding function that adds 5 to the least significant digit is adding it to the wrong digit!).

Note that the following gives the correct result:

?round(round(2390.000000*.072500,3),2)

I think there's a VFP channel for reporting bugs, though I cannot remember how to access it.

Good catch. Who knows! Correcting this error may prevent the next Jupiter probe from shooting off into bozoland!
