Give me a native (no jQuery, Prototype, etc. please) JavaScript function that converts numbers as follows:
input: 0.39, 2.5, 4.25, 5.5, 6.75, 7.75, 8.5
output: 0.39, 2.50, 4.25, 5.50, 6.75, 7.75, 8.50
E.g., in Ruby, I'd do something like this:
>> sprintf(%.2f, 2.5)
=> 2.50
The output may be a number or a string. I don't really care because I'm just using it to set innerHTML.
Thank you.
