				6716	# 1.3 If \|X\| < 16380 log(2), go to Step 2. #
				6717	# 1.4 Go to Step 8. #
				6718	# Notes: The usual case should take the branches 1.1 -> 1.3 -> 2.#
				6719	# To avoid the use of floating-point comparisons, a #
				6720	# compact representation of \|X\| is used. This format is a #
				6721	# 32-bit integer, the upper (more significant) 16 bits #
				6722	# are the sign and biased exponent field of \|X\|; the #
				6723	# lower 16 bits are the 16 most significant fraction #
				6724	# (including the explicit bit) bits of \|X\|. Consequently, #
				6725	# the comparisons in Steps 1.1 and 1.3 can be performed #
				6726	# by integer comparison. Note also that the constant #
				6727	# 16380 log(2) used in Step 1.3 is also in the compact #
				6728	# form. Thus taking the branch to Step 2 guarantees #
				6729	# \|X\| < 16380 log(2). There is no harm to have a small #
				6730	# number of cases where \|X\| is less than, but close to, #
				6731	# 16380 log(2) and the branch to Step 9 is taken. #
				6732	# #

				6742	# 2.6 Create the value Scale = 2^M. #
				6743	# Notes: The calculation in 2.2 is really performed by #
				6744	# Z := X * constant #
				6745	# N := round-to-nearest-integer(Z) #
				6746	# where #
				6747	# constant := single-precision( 64/log 2 ). #
				6748	# #
				6749	# Using a single-precision constant avoids memory #
				6750	# access. Another effect of using a single-precision #
				6751	# "constant" is that the calculated value Z is #
				6752	# #
				6753	# Z = X(64/log2)(1+eps), \|eps\| <= 2^(-24). #
				6754	# #
				6755	# This error has to be considered later in Steps 3 and 4. #
				6756	# #
				6757	# Step 3. Calculate X - N*log2/64. #
				6758	# 3.1 R := X + N*L1, #
				6759	# where L1 := single-precision(-log2/64). #
				6760	# 3.2 R := R + N*L2, #
				6761	# L2 := extended-precision(-log2/64 - L1).#
				6762	# Notes: a) The way L1 and L2 are chosen ensures L1+L2 #
				6763	# approximate the value -log2/64 to 88 bits of accuracy. #
				6764	# b) N*L1 is exact because N is no longer than 22 bits #
				6765	# and L1 is no longer than 24 bits. #
				6766	# c) The calculation X+N*L1 is also exact due to #
				6767	# cancellation. Thus, R is practically X+N(L1+L2) to full #
				6768	# 64 bits. #
				6769	# d) It is important to estimate how large can \|R\| be #
				6770	# after Step 3.2. #
				6771	# #
				6772	# N = rnd-to-int( X*64/log2 (1+eps) ), \|eps\|<=2^(-24) #
				6773	# X*64/log2 (1+eps) = N + f, \|f\| <= 0.5 #
				6774	# X64/log2 - N = f - epsX 64/log2 #
				6775	# X - Nlog2/64 = flog2/64 - eps*X #
				6776	# #
				6777	# #
				6778	# Now \|X\| <= 16446 log2, thus #
				6779	# #
				6780	# \|X - Nlog2/64\| <= (0.5 + 16446/2^(18))log2/64 #
				6781	# <= 0.57 log2/64. #
				6782	# This bound will be used in Step 4. #
				6783	# #
				6784	# Step 4. Approximate exp(R)-1 by a polynomial #
				6785	# p = R + RR(A1 + R(A2 + R(A3 + R(A4 + RA5)))) #
				6786	# Notes: a) In order to reduce memory access, the coefficients #
				6787	# are made as "short" as possible: A1 (which is 1/2), A4 #
				6788	# and A5 are single precision; A2 and A3 are double #
				6789	# precision. #
				6790	# b) Even with the restrictions above, #
				6791	# \|p - (exp(R)-1)\| < 2^(-68.8) for all \|R\| <= 0.0062. #
				6792	# Note that 0.0062 is slightly bigger than 0.57 log2/64. #
				6793	# c) To fully utilize the pipeline, p is separated into #
				6794	# two independent pieces of roughly equal complexities #
				6795	# p = [ R + RS(A2 + S*A4) ] + #
				6796	# [ S(A1 + S(A3 + S*A5)) ] #
				6797	# where S = R*R. #
				6798	# #
				6799	# Step 5. Compute 2^(J/64)exp(R) = 2^(J/64)(1+p) by #
				6800	# ans := T + ( T*p + t) #
				6801	# where T and t are the stored values for 2^(J/64). #
				6802	# Notes: 2^(J/64) is stored as T and t where T+t approximates #
				6803	# 2^(J/64) to roughly 85 bits; T is in extended precision #
				6804	# and t is in single precision. Note also that T is #
				6805	# rounded to 62 bits so that the last two bits of T are #
				6806	# zero. The reason for such a special form is that T-1, #
				6807	# T-2, and T-8 will all be exact --- a property that will #
				6808	# give much more accurate computation of the function #
				6809	# EXPM1. #
				6810	# #
				6811	# Step 6. Reconstruction of exp(X) #
				6812	# exp(X) = 2^M * 2^(J/64) * exp(R). #
				6813	# 6.1 If AdjFlag = 0, go to 6.3 #
				6814	# 6.2 ans := ans * AdjScale #
				6815	# 6.3 Restore the user FPCR #
				6816	# 6.4 Return ans := ans * Scale. Exit. #
				6817	# Notes: If AdjFlag = 0, we have X = Mlog2 + Jlog2/64 + R, #
				6818	# \|M\| <= 16380, and Scale = 2^M. Moreover, exp(X) will #
				6819	# neither overflow nor underflow. If AdjFlag = 1, that #
				6820	# means that #
				6821	# X = (M1+M)log2 + Jlog2/64 + R, \|M1+M\| >= 16380. #
				6822	# Hence, exp(X) may overflow or underflow or neither. #
				6823	# When that is the case, AdjScale = 2^(M1) where M1 is #
				6824	# approximately M. Thus 6.2 will never cause #
				6825	# over/underflow. Possible exception in 6.4 is overflow #
				6826	# or underflow. The inexact exception is not generated in #
				6827	# 6.4. Although one can argue that the inexact flag #
				6828	# should always be raised, to simulate that exception #
				6829	# cost to much than the flag is worth in practical uses. #
				6830	# #
				6831	# Step 7. Return 1 + X. #

				6928	# p := T*p #
				6929	# where T and t are the stored values for 2^(J/64). #
				6930	# Notes: 2^(J/64) is stored as T and t where T+t approximates #
				6931	# 2^(J/64) to roughly 85 bits; T is in extended precision #
				6932	# and t is in single precision. Note also that T is #
				6933	# rounded to 62 bits so that the last two bits of T are #
				6934	# zero. The reason for such a special form is that T-1, #
				6935	# T-2, and T-8 will all be exact --- a property that will #
				6936	# be exploited in Step 6 below. The total relative error #

				7978	# #
				7979	# ALGORITHM *********************************************************** #
				7980	# LOGN: #
				7981	# Step 1. If \|X-1\| < 1/16, approximate log(X) by an odd #
				7982	# polynomial in u, where u = 2(X-1)/(X+1). Otherwise, #
				7983	# move on to Step 2. #
				7984	# #
				7985	# Step 2. X = 2*k Y where 1 <= Y < 2. Define F to be the first #
				7986	# seven significant bits of Y plus 2**(-7), i.e. #
				7987	# F = 1.xxxxxx1 in base 2 where the six "x" match those #
				7988	# of Y. Note that \|Y-F\| <= 2**(-7). #
				7989	# #
				7990	# Step 3. Define u = (Y-F)/F. Approximate log(1+u) by a #
				7991	# polynomial in u, log(1+u) = poly. #
				7992	# #
				7993	# Step 4. Reconstruct #
				7994	# log(X) = log( 2*k Y ) = k*log(2) + log(F) + log(1+u) #
				7995	# by k*log(2) + (log(F) + poly). The values of log(F) are #
				7996	# calculated beforehand and stored in the program. #
				7997	# #
				7998	# lognp1: #
				7999	# Step 1: If \|X\| < 1/16, approximate log(1+X) by an odd #
				8000	# polynomial in u where u = 2X/(2+X). Otherwise, move on #
				8001	# to Step 2. #
				8002	# #
				8003	# Step 2: Let 1+X = 2*k Y, where 1 <= Y < 2. Define F as done #
				8004	# in Step 2 of the algorithm for LOGN and compute #
				8005	# log(1+X) as k*log(2) + log(F) + poly where poly #
				8006	# approximates log(1+u), u = (Y-F)/F. #
				8007	# #
				8008	# Implementation Notes: #
				8009	# Note 1. There are 64 different possible values for F, thus 64 #
				8010	# log(F)'s need to be tabulated. Moreover, the values of #
				8011	# 1/F are also tabulated so that the division in (Y-F)/F #
				8012	# can be performed by a multiplication. #
				8013	# #
				8014	# Note 2. In Step 2 of lognp1, in order to preserved accuracy, #
				8015	# the value Y-F has to be calculated carefully when #
				8016	# 1/2 <= X < 3/2. #
				8017	# #
				8018	# Note 3. To fully exploit the pipeline, polynomials are usually #
				8019	# separated into two parts evaluated independently before #
				8020	# being added up. #
