Math filters always return whole integers

So if you do:

{{ 1 | plus: 1.5 }}

You will get 2

I would recommend the (int) type castings for values returned by the Math Filters be changed to (float) to avoid this.

I'm pretty sure it's not the behaviour of the original Liquid implementation.

This is also occurring for {% assign %}, which is really frustrating if you are doing any cumulative totals with Liquid.

Can be fixed by modifying LiquidContext.class.php like so:

public function set($key, $value, $global = false)
    {
        if ( is_numeric($value) )
        {
            if ( is_float($value) )
            {
                $value = (float) $value;
            }
            else
            {
                $value = (int) $value;          
            }
        }

        if ( $global )
        ...
