### Re: Decimal to Fraction Converter

Is it supposed to be just a white box with an entry field for a number and an output box for the decimal?

Edit: Ok, when I hit the "." key everything shows up. Is it supposed to only show up after that happens? It gives me correct answers.

Did you use the euclidean algorithm to find the gcd?  If you didn't, doing so would drastically speed things up.

It sure does. It'll be pretty useful for homework or just for fun, or for some other purpose. Nice work, especially with the text design for the title of it.

Well of course ... ummm ... not. So I do now!

Thanks, Ricky it is a better tool now.

Bug patrol on the new version anyone? (I already know it looks pretty silly with long decimals.)

Oh, and Zhy ... I put an "example 1.25" as it *was* pretty unclear what to type.

Wow, the Euclidean algorithm sped this up exponentially. It works a lot better now, it instantly gives the answer.
