Spin box delta does not show update values correctly

When setting the Spin box delta to 1 and the slider exponent to 1 the value of the spine box should go up by 1s. However, the actual value is still retains decimal points and is rounded to show whole numbers. Example: If the user uses a "Get value" node on the spin box it might return 1.7983 when it's saying 2.
