ABSTRACT

        A set of elementary math  functions  (generic  on  digits  <>)
corresponding  to the FORTRAN intrinsic functions.  The implementation
of the body uses the truncated polynominals method of Cody and  Waite.
This   is  a  set  of  easily  understood  code  ment  to  be  machine
independent.  They are not particularly fast.  They could be optimized
for  particular  machines.   A fairly extensive set of test procedures
are also provided.

	The available functions and constants are:


    Pi
    E
    Log_Of_2
    Log_Of_10

    function Sign (X, Y : Floating) return Floating;
--  Returns the value of X with the sign of Y

    function Max (X, Y : Floating) return Floating;
--  Returns the algebraicly larger of X and Y
    function Min (X, Y : Floating) return Floating;
--  Returns the algebraicly smaller of X and Y

    function Truncate (X : Floating) return Floating;
--  Returns the floating value of the integer no larger than X
--  Truncates toward zero
    function Round (X : Floating) return Floating;
--  Returns the floating value of the integer nearest X

    procedure Set_Ran_Key (K : in Floating := Floating (0.0));
--  Can reset the random number generator
    function Ran return Floating;
--  A random number between zero and one

    function Sqrt (X : Floating) return Floating;
    function Cbrt (X : Floating) return Floating;
    function Log (X : Floating) return Floating;
    function Log10 (X : Floating) return Floating;
    function Exp (X : Floating) return Floating;
    function "**" (X, Y : Floating) return Floating;

    function Sin (X : Floating) return Floating;
    function Cos (X : Floating) return Floating;
    function Tan (X : Floating) return Floating;
    function Cot (X : Floating) return Floating;

    function Asin (X : Floating) return Floating;
    function Acos (X : Floating) return Floating;
    function Atan (X : Floating) return Floating;
    function Atan2 (V, U : Floating) return Floating;

    function Sinh (X : Floating) return Floating;
    function Cosh (X : Floating) return Floating;
    function Tanh (X : Floating) return Floating;
