Regex Pattern to Match Currency Format - Javascript

Question

I am newbie to javascript and struggling to write regex pattern for the requirement

2,4 = 24.00

2.4 = 2.40

2.4.5 = 2.40

2.5,5 = 2.50

2,5.7 = 25.70

45.56.34 = 45.56

13.,0 = 13.00

13,.0 = 13.00

Only digits and comma and dot are allowed. it doesn't matter how they enter But i have to convert this into proper currency format xxx,xxx,xxx,xx.xx

edited: to clarify doubts

2,4 = 24.00, but 2,5.7 = 2.50. I don't understand something. — Karolis

You have not given enough information. For example, why does 2,5.7 become 2.50 instead of 25.70, and why does 2.4.5 become 2.40 instead of 2.45 — murgatroid99

Try with:

var input  = '2,4';
var output = parseFloat( input.replace(",", ".").replace("..", ".") ).toFixed(2);

A few of these examples will take more work than that, eg 13.,0 and 45.56.34

Fair do's - wasn't expecting parseFloat to handle 45.56.34 mostly. +1
