I have a float number that I would like to display in a string way.
E.g.
0.33 should be displayed as 1/3
0.5 should be displayed as 1/2
How can I do it in objective-c with no switch? (as I could have 3/4, 2/5 etc)

3What do you mean by "no switch"? Also `0.33` isn't `1/3` is it... – trojanfoe Oct 30 '13 at 13:51

2Converting decimals to fractions and back again sounds like something you might have learned in grade school ;-) Just remember to simplify your fraction http://www.mathsisfun.com/simplifying-fractions.html – Jason Whitehorn Oct 30 '13 at 13:55

no switch - I mean using a switch case statement to find it – Dejell Oct 30 '13 at 16:15

@JasonWhitehorn the question is how to "read" it in objective-c! – Dejell Oct 30 '13 at 16:22

There's no objective-c way to do this, you'll have to implemente it yourself and find an algorightm.
What about trying combinations of A/B where A,B from 0 to 10, until you reach the number?

1Using "Continued Fractions", as in the answer to http://stackoverflow.com/questions/95727/how-to-convert-floats-to-human-readable-fractions (link given by Javi above), is *much* faster than trying all combinations. – Martin R Oct 30 '13 at 14:16
