In jQuery, what's the best way of formatting a number to 2 decimal places?
This is what I have right now:
$("#number").val(parseFloat($("#number").val()).toFixed(2));
It looks messy to me. I don't think I'm chaining the functions correctly. Do I have to call it for each textbox, or can I create a separate function?

Convert decimal mark when reading numbers as input
I have a CSV file with data reading that I want to read into Python. I get lists that contain strings like "2,5". Now doing float("2,5") does not work, because it has the wrong decimal mark.
