NAME

	IEEEDPSincos -- compute the arc tangent of a floating point number

SYNOPSIS

	  x   = IEEEDPSincos( z ,  y  );
d0/d1 a0 d0/d1
double x,y,*z;

FUNCTION

	Compute sin and cosine of y in IEEE double precision.
Store the cosine in *z. Return the sine of y.

INPUTS

	y - IEEE double precision floating point value
z - pointer to IEEE double precision floating point number

RESULT

	x - IEEE double precision floating point value

BUGS

	Not very fast if no FPU is available. Otherwise, it might be
faster than calling IEEEDPSin() and IEEEDPCos() separately.
