Why is toFixed(2) Rounding Incorrectly for Certain Decimal Values?

Javascript toFixed Rounding Discrepancies

toFixed(2) is not rounding up for certain decimal values, displaying 859.38 instead of 859.39 in the example provided. This discrepancy can be attributed to variations in browser implementations of the toFixed() method.

To circumvent this issue and ensure consistent rounding across browsers, consider utilizing the toFixed10() method recommended by blg. This method provides accurate rounding even for extended precision values.

Here's an updated code snippet that incorporates toFixed10():

function toFixed(num, precision) {
    return (+(Math.round(+(num + 'e' + precision)) + 'e' + -precision)).toFixed(precision);
}
...
$('#lblTotalSprice').text('$' + addCommas(toFixed(currSprice, 2)));
$('#lblTotalPrice').text('$' + addCommas(toFixed(currPrice, 2)));
$('#lblTotalDiscount').text('$' + addCommas(toFixed(currDiscount, 2)));
$('#lblTotalDeposit').text('$' + addCommas(toFixed(currDeposit, 2)));
