Javascript Regex for decimal

Question

I need a regex for a 5 digit integer number with 2 decimals.

These would be correct:

12345.12
09856.99
45123.00

These wouldn't:

123.12
12345.6
98652

Use this regex it will work

var regex = /^\d{5}\.\d{2}$/;
var num = '23445.09';
console.log(regex.test(num));  // True

var num2 = '12345.6'
console.log(regex.test(num));  // False

There's no need for the `?` either? It has to have 2 digits after decimal point. – MinusFour Sep 15 '16 at 22:22

I would change the line to `var regex = /^\d{5}\.\d{2}$/;` – pwagner Sep 15 '16 at 22:24

This would be correct : /^\d{5}\.\d{2}$/

var value = 12345.12;
value.toString().match(/^\d{5}\.\d{2}$/); // ['12345.12']

var value = 98652;
value.toString().match(/^\d{5}\.\d{2}$/); // null

Same as the other answer, you need to escape your dot. Try it with `value = 12345678` – Alberto Rivera Sep 15 '16 at 22:25
Thanks for that, you right. I edited my answer ;) – Robiseb Sep 15 '16 at 22:31
