libcss actual values

Hi,

I was trying out libcss and found that the following code snippet returns value multiplied by 1024.

css_unit unit;

css_fixed val;
css_computed_margin_top(styles[0], &val, &unit);
std::cout << val << std::endl;

For example: if my margin is set to 2px, returned Val would be 2048.

Is there a function that can return actual values (Not bit-shifted values)?

if not, then could you please confirm that all CSS values are left-shifted by 10 bits. in that case, I can right shift for all the values. 

Regards
