[Python-checkins] CVS: python/dist/src/Objects floatobject.c,2.103,2.104

[Tim Peters]

Update of /cvsroot/python/python/dist/src/Objects
In directory usw-pr-cvs1:/tmp/cvs-serv21887/python/Objects

Modified Files:
	floatobject.c 
Log Message:
float_abs() again:  Guido pointed out that this could screw up in the
presence of NaNs.  So pass the issue on to the platform libm fabs();
after all, fabs() is a std C function because you can't implement it
correctly in portable C89.
