-// History
-//==============================================================
-// 08/25/00 Initial version
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 09/06/02 Improved performance; no inexact flags on exact cases
-// 01/29/03 Added missing } to bundle templates
-// 12/16/04 Call error handling on underflow.
-// 03/31/05 Reformatted delimiters between data tables
-//
-// API
-//==============================================================
-// double exp10(double)
-//
-// Overview of operation
-//==============================================================
-// Background
-//
-// Implementation
-//
-// Let x= (K + fh + fl + r)/log2(10), where
-// K is an integer, fh= 0.b1 b2 b3 b4 b5,
-// fl= 2^{-5}* 0.b6 b7 b8 b8 b10 (fh, fl >= 0),
-// and |r|<2^{-11}
-// Th is a table that stores 2^fh (32 entries) rounded to
-// double extended precision (only mantissa is stored)
-// Tl is a table that stores 2^fl (32 entries) rounded to
-// double extended precision (only mantissa is stored)
-//
-// 10^x is approximated as
-// 2^K * Th [ f ] * Tl [ f ] * (1+c1*e+c1*r+c2*r^2+c3*r^3+c4*r^4),
-// where e= (x*log2(10)_hi-RN(x*log2(10)_hi))+log2(10)_lo*x
-
-// Note there are only 22 non-zero values that produce an exact result:
-//  1.0, 2.0, ... 22.0.
-// We test for these cases and use s1 to avoid setting the inexact flag.
-
-// Special values
-//==============================================================
-// exp10(0)= 1
-// exp10(+inf)= inf
-// exp10(-inf)= 0
