	IEEEDPLog -- compute the natural logarithm of a floating point number

SYNOPSIS

	  x   = IEEEDPLog(  y  );
	d0/d1	          d0/d1
	double	x,y;

FUNCTION

	Compute ln(y) in IEEE double precision

INPUTS

	y - IEEE double precision floating point value

RESULT

	x - IEEE double precision floating point value

BUGS

	Might have returned bare nonsense if the argument was out of range
	for pre-V45 releases. Returns NAN for negative arguments or -INF for 
	an argument of zero.
