Hi there,

I found some realy strange behavior in the round() funtion in VFP7 and VFP8

When i round 147.3250000000 on 2 decimal places i get 147.33 as result (as aspected).
when i round 147.32500000000 on 2 decimal places i get 147.32!?!? :

?round(147.3250000000,2)
?round(147.32500000000,2)

After this i tried some other things to find out what is wrong here:

for lnValueBasic = 1 to 200
lnValue = lnValueBasic + 0.325
lnValueLong = round(lnValue,11)
lnValueRound = round(lnValueLong,2)
lnDifferenceBasic_Round=lnValueRound-lnValueBasic && has to be 0.33
if lnDifferenceBasic_Round <> 0.33
messagebox(lnValueBasic)
endif
endfor

If you run this piece of code you'll see that for lnValueBasic being between 128 and 163 the round()-function does not work properly.

Is somebody familiar with this problem?
Is this a bug?
