commit 9b6ad20132565202c72dec2dd2d8c6ee287c1601
Author: Raymond Toy <toy.raymond at gmail.com>
Date: Mon Aug 25 19:31:03 2014 -0700
Deprecate FLOAT-TRAPPING-NAN-P in favor of FLOAT-SIGNALING-NAN-P.
These numbers are called signaling, not trapping NaN in almost all
usages.
* code/exports.lisp:
* Export FLOAT-SIGNALING-NAN-P.
* code/float.lisp:
* Implement FLOAT-SIGNALING-NAN-P.
* Make FLOAT-TRAPPING-NAN-P an inline call to the
FLOAT-SIGNALING-NAN-P and add a docstring to say it is
deprecated.
* code/print.lisp:
* Print "Signaling" instead of "Trapping".
* i18n/locale/cmucl.pot:
* Regenerated due to the changes in docstrings.
