  32  * 1. they are more optimal as they only evaluate a & b once by creating a
  33  *    a variable of each type on the local stack.
  34  * 2. they fix potential errors due to side-effects where a and b were
  35  *    evaluated twice, i.e. MIN(i++,j++)
  36  *
  37  * @note b could be cast to a's type, to help with usage where the code
  38  *       compares signed and unsigned types.
