- * DOUBLE PRECISION (VAX D FORMAT 56 bits or IEEE DOUBLE 53 BITS)
- * KERNEL FUNCTION FOR LOG; TO BE USED IN LOG1P, LOG, AND POW FUNCTIONS
- * CODED IN C BY K.C. NG, 1/19/85; 
- * REVISED BY K.C. Ng, 2/3/85, 4/16/85.
- *
- * Method :
- *	1. Polynomial approximation: let s = x/(2+x). 
- *	   Based on log(1+x) = log(1+s) - log(1-s)
- *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
- *
- *	   (log(1+x) - 2s)/s is computed by
- *
- *	       z*(L1 + z*(L2 + z*(... (L7 + z*L8)...)))
- *
- *	   where z=s*s. (See the listing below for Lk's values.) The 
- *	   coefficients are obtained by a special Remez algorithm. 
- *
- * Accuracy:
- *	Assuming no rounding error, the maximum magnitude of the approximation 
- *	error (absolute) is 2**(-58.49) for IEEE double, and 2**(-63.63)
- *	for VAX D format.
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following constants.
- * The decimal values may be used, provided that the compiler will convert
- * from decimal to binary accurately enough to produce the hexadecimal values
- * shown.
