Erm... no. Hexadecimal floating-poing ("hexfloat") is a side-effect of
C99/XPG6 compilance and has some importamce if you need to pass accurate
floating-point values around between applications (that's why
ksh93-integration update1 added "typeset -X" (see
http://mail.opensolaris.org/pipermail/ksh93-integration-discuss/2009-January/006761.html)
to have direct access to hexfloat values, avoiding the need to go
through $ printf "%a\n" varname # each time).
Or short: Each application which handles floating-point values is
_required_ to support the hexfloat format.
