What Is Hydrostatic Equilibrium?
A volume of fluid, which can be a gas or a liquid, is said to be in hydrostatic equilibrium when the downward force exerted by gravity is balanced by an upward force exerted by the pressure of the
fluid.

If I'm understanding this correctly, you're taking some 6-digit number abcdef and using that to get a new number, given by abc + (de + f/2)/100.
In your example, 145725 would convert to 145 + (72 + 5/2)/100 = 145.745.
