Depending on the history of the code it is either stupidity or brilliance.
It could just be the result of many changes that made the function the way
it is now (stupidity), or the code is trying to play with floating-point
accuracy in a complex way (brilliance). It is impossible to tell without
comparing the function and its simplified twin over a significant range of
input values.
