Allow fraction numbers in quantity field

You can use decimal fractions (0.5, 0.25 etc), which are easier to parse and do the multiplication on when using a modified yield.

I will be working on allowing fractions (1/4, 1/2, 1/8, etc..) to be used in the input and on a setting to choose how they are displayed in the recipe admin area.

Patch forthcoming.

Patch attached.

This allows users to use fractions like "1/2" or "1/8" when entering ingredients. They are converted to decimal when being stored in the database.

I'll open a new issue for allowing an admin setting to determine how fractions are displayed when viewing a recipe.

Looks good, but waiting until it can handle stuff like "1 1/2" before applying.

Should be fixed now.

Applied, thanks.

Nice patch. One little problem when trying to display 1/3 (and I guess any 3, 6, 9, etc. fraction), though.

I get the following fraction: 1026405035⁄1215752192T

Attached a patch against CVS that will fix the conversion issues with thirds, sixths, ninths, and twelfths.

It's not as elegant as a mathematical formula, but effective for the most likely to be encountered fractions.

Small change to make sure you don't get numbers like 23 1/1 instead of 24.

Thanks moonray. My dev drupal database is currently a bit messed up from some other stuff I was doing, but I shall get that cleared up and test/apply your patch within the next few days. From looking at it though, doesn't the substr rely on there being less than 10 whole units?

I'm not quite sure what you mean with your comment about substr? If you explain, and it's an issue, I'll try and fix it. :-)

Well, I didn't test it out yet, but doing a substr($whatever, 2, 4) doesn't seem like it would get the right part of the string, if $whatever was "10.3333". (Admittedly fairly unlikely for a recipe, but possible if someone changes the yield to something large.)

Ah! Now I understand.

$conversionstr = substr((string) ($conversion - floor($conversion)), 2, 4);

The $conversion - floor($conversion) part removes all digits before the decimal point, so you know that you always have 0.xxxxxxxx, which is why I can safely do a substr. No issue here. :-)

Ah great. Sorry it took me so long, but I have now finally tried it, and checked it in.
