Format a number to two decimal places
javascript, number-formatting, numbers
Solution
input = 0.3;
output = input.toFixed(2);
// output: 0.30
A newer option, which supports rounding:
new Intl.NumberFormat('en-US', {
minimumFractionDigits: 2,
maximumFractionDigits: 2
}).format(1.005)
// Outputs: 1.01
Problem
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.
