Do you know a good algorithm to convert 0.125 into 1/8? err, you interpret it as 125/1000 and then you simplify ? there's also an algorithm to convert decimal numbers of infinite length, but with a repeating part ( which means the decimal representations of all rational numbers ) into fractions... I think the idea was to divide the repeating part by a number which you write down as x 9's where x is the length of the repeating part ( that's the best i can explain it in english :). E.g. 0,111... would become 1/9 . 0.1212... would become 12/99 etc. This is the way they explained it to us in high school, i'm sure there's an easy way to write this down in code... cheers domi -- I'm ANN LANDERS!!
