Issue with ticks on using decimal ranges

[palanii]

We are using angular slider with some decimal steps. This is the code we are using:

$scope.slider = {
value: 1,
options: {
useDecimal: true,
orientation: 'horizontal',
min: 0.5,
max: 3,
range: 'min',
step: 0.5,
tick: true,
change: refreshSwatch
}
};

While implementing the ticks, we are not getting any ticks. In postLink method we are calculating the total ticks by.
var total = parseInt(parseInt(options['max'])/parseInt(options['step']));
Its returning NaN in our case. Here we'll have to check useDecimal flag before calculating the total. I've replaced this by below and i can able to see ticks on the screen.
var total = parseInt(options['max']/options['step']);

Is this something needs to be fixed in the library..?

Thanks,
