diff Objects/floatobject.c @ 39642:981181d2a4fe legacy-trunk
Reverting the patch that tried to fix the issue whereby x**2 raises
OverflowError while x*x succeeds and produces infinity; apparently
these inconsistencies cannot be fixed across ``all'' platforms and
there's a widespread feeling that therefore ``every'' platform
should keep suffering forevermore. Ah well.
