JavaScript: formatting number with exactly two decimals
Now that I have got a bit of script to add values in to a div with a total in it, I then try to divide the values by 100 to give me a decimal number (to make it look like currency).
After this the script works and gives me a nice decimal float, sometimes though a large recurring number comes after, I want to limit this to two decimals using the script i already have so was wondering if someone could implement something into my current script.
$(document).ready(function() {
$('.add').click(function() {
$('#total').text(parseFloat($('#total').text()) + parseFloat($(this).data('amount'))/100);
});
})

You need to use the .toFixed() method
It takes as a parameter the number of digits to show after the decimal point.
$(document).ready(function() {
$('.add').click(function() {
var value = parseFloat($('#total').text()) + parseFloat($(this).data('amount'))/100
$('#total').text( value.toFixed(2) );
});
})
you can use just javascript for it
var total =10.8
(total).toFixed(2); 10.80
alert(total.toFixed(2)));
Try to use this
parseFloat().toFixed(2)
