Malaysia recently introduce a rounding mechanism for trading to remove the need for 1 cent in the market, but with this new implementation it cause us web developer more task to make it work with our current application.

The Rounding Mechanism is a method whereby the total bill amount (including goods and services subject to tax) is rounded upwards or downwards to the nearest multiple of 5 sen. In this regard, total bill amount that ends in 1, 2, 6 and 7 sen will be rounded down while 3, 4, 8 and 9 sen will be rounded up to the nearest multiple of 5 sen.

For example, a total bill amounting to RM82.01 will be rounded down to RM82.00. If it amounts to RM82.04, it will be rounded up to RM82.05.

This is actually just a modification from JavaScript Round To Nearest Number by Talk in Code. Instead of getting the nearest digit, we will actually get the rounding to the next nearest number.

function roundNextNearest(num, acc) {
    if ( acc < 0 ) {
        return Math.round(num*acc)/acc;
    } else {
        var value = Math.round(num/acc)*acc;
        if (value < num) {
            value += acc;
        }
    }
    return value;
}

This is very simple approach to validate date input in DD-MM-YYYY format.

var validate_date = function(date) {
	if ( date.match(/^(\d{1,2})\-(\d{1,2})\-(\d{4})$/) ) {
		var dd = RegExp.$1;
		var mm = RegExp.$2;
		var yy = RegExp.$3;

		// try to create the same date using Date Object
		var dt = new Date(parseFloat(yy), parseFloat(mm)-1, parseFloat(dd), 0, 0, 0, 0);
		// invalid day
		if ( parseFloat(dd) != dt.getDate() ) { return false; }
		// invalid month
		if ( parseFloat(mm)-1 != dt.getMonth() ) { return false; }
		// invalid year
		if ( parseFloat(yy) != dt.getFullYear() ) { return false; }

		// everything fine
		return true;
	} else {
		// not even a proper date
		return false;
	}
};

Here a simple usage of hover on table compatible with all modern browser with a little help from jQuery.

jQuery(function($) {
	$("table tbody tr").hover(function() {
		$(this).addClass("hover");
	}, function() {

});

As for the Stylesheet, you can add
