Brian,

Off the top of my head, I'd say 1 / .25 = 4, which is your denominator. Divide 1 by your decimal and you get the denominator x in the expression 1/x.

For 2.25 (and other mixed numbers), use this approach:
1. Divide 1 by the decimal portion to get your denominator
2. multiply the denominator by the integer portion, add 1, that's your numerator.

>Has anyone ever seen a routine that will take a decimal number, and output a string that is formatted as a fraction. For instance, send in .25, and it will return "1/4". Any help would be great.
