- *
- *	_XcmsCosine   double precision cosine
- *
- *  KEY WORDS
- *
- *	cos
- *	machine independent routines
- *	trigonometric functions
- *	math libraries
- *
- *  DESCRIPTION
- *
- *	Returns double precision cosine of double precision
- *	floating point argument.
- *
- *  USAGE
- *
- *	double _XcmsCosine (x)
- *	double x;
- *
- *  REFERENCES
- *
- *	Computer Approximations, J.F. Hart et al, John Wiley & Sons,
- *	1968, pp. 112-120.
- *
- *  RESTRICTIONS
- *
- *	The sin and cos routines are interactive in the sense that
- *	in the process of reducing the argument to the range -PI/4
- *	to PI/4, each may call the other.  Ultimately one or the
- *	other uses a polynomial approximation on the reduced
- *	argument.  The sin approximation has a maximum relative error
- *	of 10**(-17.59) and the cos approximation has a maximum
- *	relative error of 10**(-16.18).
- *
- *	These error bounds assume exact arithmetic
- *	in the polynomial evaluation.  Additional rounding and
- *	truncation errors may occur as the argument is reduced
- *	to the range over which the polynomial approximation
- *	is valid, and as the polynomial is evaluated using
- *	finite-precision arithmetic.
- *
- *  PROGRAMMER
- *
- *	Fred Fish
- *
- *  INTERNALS
- *
- *	Computes cos(x) from:
- *
- *		(1)	Reduce argument x to range -PI to PI.
- *
- *		(2)	If x > PI/2 then call cos recursively
- *			using relation cos(x) = -cos(x - PI).
- *
- *		(3)	If x < -PI/2 then call cos recursively
- *			using relation cos(x) = -cos(x + PI).
- *
- *		(4)	If x > PI/4 then call sin using
- *			relation cos(x) = sin(PI/2 - x).
- *
- *		(5)	If x < -PI/4 then call cos using
- *			relation cos(x) = sin(PI/2 + x).
- *
- *		(6)	If x would cause underflow in approx
- *			evaluation arithmetic then return
- *			sqrt(1.0 - x**2).
- *
- *		(7)	By now x has been reduced to range
- *			-PI/4 to PI/4 and the approximation
- *			from HART pg. 119 can be used:
- *
- *			cos(x) = ( p(y) / q(y) )
- *			Where:
- *
- *			y    =	x * (4/PI)
- *
- *			p(y) =  SUM [ Pj * (y**(2*j)) ]
- *			over j = {0,1,2,3}
- *
- *			q(y) =  SUM [ Qj * (y**(2*j)) ]

+ *

+ *  RESTRICTIONS

+ *

+ *	The sin and cos routines are interactive in the sense that

+ *	in the process of reducing the argument to the range -PI/4

+ *	to PI/4, each may call the other.  Ultimately one or the

+ *	other uses a polynomial approximation on the reduced

+ *	argument.  The sin approximation has a maximum relative error

+ *	of 10**(-17.59) and the cos approximation has a maximum

+ *	relative error of 10**(-16.18).

+ *

+ *	These error bounds assume exact arithmetic

+ *	in the polynomial evaluation.  Additional rounding and

+ *	truncation errors may occur as the argument is reduced

+ *	to the range over which the polynomial approximation

+ *	is valid, and as the polynomial is evaluated using

+ *	finite-precision arithmetic.

+ *

+ *  PROGRAMMER

+ *

+ *	Fred Fish

+ *

+ *  INTERNALS

+ *

+ *	Computes sin(x) from:

+ *

+ *	  (1)	Reduce argument x to range -PI to PI.

+ *

+ *	  (2)	If x > PI/2 then call sin recursively

+ *		using relation sin(x) = -sin(x - PI).

+ *

+ *	  (3)	If x < -PI/2 then call sin recursively

+ *		using relation sin(x) = -sin(x + PI).

+ *

+ *	  (4)	If x > PI/4 then call cos using

+ *		relation sin(x) = cos(PI/2 - x).

+ *

+ *	  (5)	If x < -PI/4 then call cos using

+ *		relation sin(x) = -cos(PI/2 + x).

+ *

+ *	  (6)	If x is small enough that polynomial

+ *		evaluation would cause underflow

+ *		then return x, since sin(x)

+ *		approaches x as x approaches zero.

+ *

+ *	  (7)	By now x has been reduced to range

+ *		-PI/4 to PI/4 and the approximation

+ *		from HART pg. 118 can be used:

+ *

+ *		sin(x) = y * ( p(y) / q(y) )

+ *		Where:

+ *

+ *		y    =  x * (4/PI)

+ *

+ *		p(y) =  SUM [ Pj * (y**(2*j)) ]

+ *		over j = {0,1,2,3}

+ *

+ *		q(y) =  SUM [ Qj * (y**(2*j)) ]

+ *		over j = {0,1,2,3}

+ *

+ *		P0   =  0.206643433369958582409167054e+7
