Well. It is not that easy to go from decimal to fraction. Because 1/2 = 0.5 = 2/4 = 4/8, etc. So if you have 0.5 how do you know which fraction is the correct one?

But what you could do is:

lnCnt = 0
lnDec = 0.6
do while .T.
  lnCnt = lnCnt + 1
  lnResult = lnCnt * lnDec
  if lnResult == int(lnResult)
    exit
  endif
enddo

? "Fraction: " + allt(str(lnResult))+"/"+allt(str(lnCnt))

That should give you the first fraction met.
