Answer 1

Multiply by 4, round to integer, divide by 4 and format with two decimals.

Edit Any reason for the downvotes? At least leave a comment to know what should be improved.

Answer 2

Here’s an implementation of what rslite said:

var number = 5.12345;
number = (Math.round(number * 4) / 4).toFixed(2);
