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
