Why on earth would they create a named constant for 1.5F, but not for 0x5f3759df?

What would you name it?

    #define AND_THEN_A_MIRACLE_OCCURS (0x5f3759df)

Fair enough. Still, it seems silly to name a constant THREE_HALVES. What information does that add over 1.5? What happens if you change it and it becomes wrong?
