Subject: [Stds-754] Amendment to Motion21

I would like to amend motion21. The modified text would read:

 "If G0 through G4 are 11111, then v is NaN regardless
 of S. Furthermore, if G5 is 1, then r is sNaN; otherwise
 r is qNaN.  The remaining bits of G are ignored, and T
 constitutes the NaN's payload, which can be used to
 distinguish various NaNs.

 The NaN payload is encoded similarly to finite numbers
 described below, with G treated as though all bits were
 zero.  The payload corresponds to the significand of
 finite numbers, interpreted as an integer with a maximum
 value of 10^(3*J)-1, and the exponent is ignored (it is
 treated as if it were zero).  A NaN is in its preferred
 (canonical) representation if the bits G6 -- Gw+4 are
 zero and the encoding of the payload is canonical." 

Thanks to Michel Hack and Mike Cowlishaw for helping with this improved
wording.
