Depends on #116

Sorry - after further investigation (surely, right after hitting 'submit') I found the embedded schema on the page, which is the source for the float value. My bad.

"recipeIngredient": [
"0.33333334326744 cup white sugar",

I reopen this issue as a rounding feature for all recipes or all ingredients of one recipe might be something useful. However, we need to split the ingredients into numbers, units, etc in order to do calculations with the values.
