 \section{Small Constants}
-Setting mp\_ints to small constants is a relatively common operation.  To accommodate these instances there are two
-small constant assignment functions.  The first function is used to set a single digit constant while the second sets
-an ISO C style ``unsigned long'' constant.  The reason for both functions is efficiency.  Setting a single digit is quick but the
