Integer Functions
-----------------

   The functions described in this section all operate on, and return,
integer values.

 - Function: quotient dividend divisor
     Return the integer part of dividing DIVIDEND by DIVISOR.

 - Function: remainder dividend divisor
     Returns the integer remainder from dividing the DIVIDEND by
     DIVISOR. The remainder is either zero or has the same sign as
     DIVIDEND.

 - Function: modulo dividend divisor
 - Function: mod dividend divisor
     Return the value of DIVIDEND modulo DIVISOR. Unlike the
     `remainder' function the `modulo' function always has the sign of
     the DIVISOR, not of the DIVIDEND

 - Function: gcd args...
     Returns the greatest common divisor of the integers ARGS...  If no
     arguments are given, returns zero.

 - Function: lcm args...
     Return the lowest common multiple of the integers ARGS... If no
     arguments are given, returns one.
