-//*********************************************************************
-// 02/02/00 Initial version
-// 02/16/00 The error tag for coshf overflow changed to 65 (from 64).
-// 04/04/00 Unwind support added
-// 08/15/00 Bundle added after call to __libm_error_support to properly
-// set [the previously overwritten] GR_Parameter_RESULT.
-// 05/07/01 Reworked to improve speed of all paths
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 11/15/02 Improved algorithm based on expf
-// 03/31/05 Reformatted delimiters between data tables
-//
-// API

-// Overview of operation
-//*********************************************************************
-// Case 1: 0 < |x| < 0.25
-// Evaluate cosh(x) by a 8th order polynomial
-// Care is take for the order of multiplication; and A2 is not exactly 1/4!,
-// A3 is not exactly 1/6!, etc.
-// cosh(x) = 1 + (A1*x^2 + A2*x^4 + A3*x^6 + A4*x^8)
-//
-// Case 2: 0.25 < |x| < 89.41598
-// Algorithm is based on the identity cosh(x) = ( exp(x) + exp(-x) ) / 2.
-// The algorithm for exp is described as below. There are a number of
-// economies from evaluating both exp(x) and exp(-x). Although we
-// are evaluating both quantities, only where the quantities diverge do we
-// duplicate the computations. The basic algorithm for exp(x) is described
-// below.
-//
-// Take the input x. w is "how many log2/128 in x?"
-// w = x * 64/log2
-// NJ = int(w)
-// x = NJ*log2/64 + R
-
-// NJ = 64*n + j
-// x = n*log2 + (log2/64)*j + R
-//
-// So, exp(x) = 2^n * 2^(j/64)* exp(R)
-//
-// T = 2^n * 2^(j/64)
-// Construct 2^n
-// Get 2^(j/64) table
-// actually all the entries of 2^(j/64) table are stored in DP and
-// with exponent bits set to 0 -> multiplication on 2^n can be
-// performed by doing logical "or" operation with bits presenting 2^n
-
-// exp(R) = 1 + (exp(R) - 1)
-// P = exp(R) - 1 approximated by Taylor series of 3rd degree
-// P = A3*R^3 + A2*R^2 + R, A3 = 1/6, A2 = 1/2
-//
-
-// The final result is reconstructed as follows
-// exp(x) = T + T*P
