As a manufacturer we required a fraction conversion function and not a 1/25 fraction but an actual 1/32 or 1/16 fraction, you know, one that shows up on a tape measure. I thought I would share the code that I came up with and would appreciate any critique of the code. I have two different functions, one for 1/32 and on for 1/16. I do realize that I could have simply checked the 'Accuracy' variable but there are many users who prefer the software to work in 6 or 7 places of accuracy but print in either 1/16 or 1/32 increments. I've also added a .01 to the value since I didn't want to write a extra code to look for .9999, .4999, .65, etc .... I couldn't really find a good rounding function and this worked well for our application.
Thanks in advance for your critique, I'm not terribly familiar with this language yet.
