Hi @rohitbhatia2691!

Try this regex (demo):

$('#keyboard').keyboard({
    layout: 'num',
    restrictInput: true,
    change : function(e, keyboard, el) {
        var val = keyboard.$preview.val().match(/(\d+)(\.\d{0,2})?/);
        if (val) {
            keyboard.$preview.val( val.slice(1).join('') );
        }
    }
});

I updated the demo to remember the caret position, so the caret won't jump to the end once the value gets updated. This happens when you try to type numbers to the left of an existing decimal value (new demo):

$('#keyboard').keyboard({
    layout: 'num',
    restrictInput: true,
    change : function(e, keyboard, el) {
        var val = keyboard.$preview.val().match(/(\d+)(\.\d{0,2})?/);
        if (val) {
            keyboard.$preview
                .val(val.slice(1).join(''))
                .caret( keyboard.lastCaret.start, keyboard.lastCaret.end );
        }
    }
});
