ABSTRACT

Cody-Waite 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;
