Convert currency to decimal in PHP and JavaScript

Question

I'm looking for the shortest/easiest way to achieve this.

var savings = <?php echo $list_price ?> - discount_price;

savings: 1.00

$list_price: '$10.00'; discount_price: '$9.00';

Cheers.

Answer 1

Not sure what you're asking here - could you post an example of what you want to achieve?

Answer 2

isnt currency by default represented as a "decimal" (of sorts)

$1.00 = 1.00
0.50c = 0.5

Answer 3

Maybe this is the answer?

var savings = parseFloat(<?php echo $list_price ?>) - discount_price;

Answer 4

Your question is your answer ..! Am I missing anything ?

Answer 5

var savings = parseFloat('<?php echo $list_price ?>'.substr(1)) -
  parseFloat(discount_price.substr(1));

This parses the string as a number, skipping the first characters (dollar).
