in reply to Re^5: return +0 (-.0?)
in thread return +0

It depends on the math libraries? They're different here, at least:

sidhekin@blackbox[23:22:41]~$ perl -MDevel::Peek -le 'Dump(.0)' SV = NV(0x816e490) at 0x814dce4 REFCNT = 1 FLAGS = (PADBUSY,PADTMP,NOK,READONLY,pNOK) NV = 0 sidhekin@blackbox[23:22:51]~$ perl -MDevel::Peek -le 'Dump(-.0)' SV = NV(0x816e4a0) at 0x814dd20 REFCNT = 1 FLAGS = (PADBUSY,PADTMP,NOK,READONLY,pNOK) NV = -0 sidhekin@blackbox[23:22:53]~$

print "Just another Perl ${\(trickster and hacker)},"
The Sidhekin proves Sidhe did it!
