-// History
-//==============================================================
-// 07/27/00 Initial version
-// 08/15/00 Bundle added after call to __libm_error_support to properly
-// set [ the previously overwritten ] GR_Parameter_RESULT.
-// 02/02/01 Added libm_error_support calls for underflow
-// 05/20/02 Cleaned up namespace and sf0 syntax
-// 02/06/03 Reordered header: .section, .global, .proc, .align
-// 05/07/03 Reformatted assembly source
-//
-// API

-// Overview of operation
-//==============================================================
-// Background
-//
-// Implementation
-//
-// Let x= K + f + r, where
-// K is an integer, f= 0.b1 b2... b8 (f>= 0),
-// and |r|<2^{-8}
-// T is a table that stores 2^f (256 entries) rounded to
-// double extended precision (only mantissa is stored)
-// D stores (2^f/T [ f ] - 1), rounded to single precision
-//
-// 2^x is approximated as
-// 2^K * T [ f ] * (1+D [ f ] +c1*r+c2*r^2+...+c6*r^6)
