The functions $EqualTolerance and $SameQToleranceexists in the
Experimantel context both in Mathematica 5.2 and in later versions. But
while in 5.2 I get
In[1]:=
Experimental`$EqualTolerance
Out[1]=
2.10721
In 7.01 I get:
In[44]:= Experimental`$EqualTolerance
Out[44]= Experimental`$EqualTolerance
Further more, it seems that although the function name $EqualTolerance
has been retained in the Experimental context, the function itself no
longer does anything. Compare:
Mathematica 5.2
In[9]:=
Block[{Experimental`$EqualTolerance =16}, 1. == 2.]
Out[9]=
True
Mathematica 7.01
In[58]:= Block[{Experimental`$EqualTolerance = 16}, 1. == 2.]
Out[58]= False
Was keeping Experimental`$EqualTolerance while removing its definition
in Mathematica 7 just an oversight or does it still serve some purpose?
And has the functionality been transferred to some other function?
