RE: SQL user function to turn a decimal number to a fraction

["Paul Therrien" <paultherrien@xxxxxxxxxxxxxxxxxx>]

I am curious.  Are the numbers coming in always going to result in clean fractions?  
What would be the resulting fraction if the incoming number was 0.03126?  1/31.98976; 1/31.99?; 1/32?
