Editing Salt/Sodium content field does not work correctly with fractions without leading zero

[aquilax]

Describe the bug

On the product edit page, setting fractional salt or sodium value without leading zero produces incorrect calculated value for the corresponding field.

To Reproduce

1. Open a product edit page
2. Set Salt content to .53 and move to the next field
3. Sodium content is calculated as .21.200000000000003

Expected behavior

Calculation to work without setting leading zero to the fraction.

Additional context

	function swapSalt(from, to, multiplier) {
		var source = from.val().replace(",", ".");
		var regex = /^(.*?)([\d]+(?:\.[\d]+)?)(.*?)$/g;
		var match = regex.exec(source);
		if (match) {
			var target = match[1] + (parseFloat(match[2]) * multiplier) + match[3];
			to.val(target);
		} else {
			to.val(from.val());
		}
	}

The swap salt function concatenates match[1] in front of the result which leads to having the decimal point twice.
