Convert Fraction String to Decimal?

Question

I\'m trying to create a javascript function that can take a fraction input string such as \'3/2\' and convert it to decimal—either as a string \'1.5\'

Answer 1

Here is the bare bones minimal code needed to do this:

var a = "3/2";
var split = a.split('/');
var result = parseInt(split[0], 10) / parseInt(split[1], 10);
alert(result); // alerts 1.5

Things to consider:

• division by zero
• if the user gives you an integer instead of a fraction, or any other invalid input
• rounding issues (like 1/3 for example)
