If you are just interested in dividing by 2, then just take (n 1) / 2 to keep it in integer math. All that remains now is adding 1 to this quotient, which, incidentally, is floor((float) dividend / (float) divisor).

An overarching evolutionary theory which can provide an explanation for the above mechanisms and strategies adopted by individuals which leads to age disparity in relationships is called Life History theory, Life History theory posits that individuals have to divide energy and resources between activities (as energy and resources devoted to one task cannot be used for another task) and this is shaped by natural selection.
Parental Investment Theory refers to the value that is placed on a potential mate based on reproductive potential and reproductive investment.
