ABSTRACT

CodyWaite Math Library
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 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;
