While unsure about what is going on, i must admit that was a totally unexpected result
i was wondering if you had run into something called a dualvar.
Resultuse strict; use warnings; $|=1; use Scalar::Util qw(dualvar); use Devel::Peek; print "nv1\n"; my $nv1 = 1e-2 ;Dump($nv1); print "nv1: +$nv1 ".($nv1+0)."\n"; Dump($nv1); print "dv2\n"; my $dv2 = dualvar( 1e-2, "hi" );Dump($dv2); print "dv2: +$dv2 ".($dv2+0)."\n"; Dump($dv2);
Of particular interest here is the line "dv2:hi 0.01" where in string context you get hi, but in numeric you get 0.1. But it doesnt seem that dualvars are your problem.nv1 SV = NV(0xa7c024) at 0xa3e614 REFCNT = 1 FLAGS = (PADMY,NOK,pNOK) NV = 0.01 nv1:0.01 0.01 SV = PVNV(0x3f7364) at 0xa3e614 REFCNT = 1 FLAGS = (PADMY,NOK,pIOK,pNOK) IV = 0 NV = 0.01 PV = 0xa959d4 "0.01"\0 CUR = 4 LEN = 36 dv2 SV = PVNV(0x3f73c4) at 0xa8facc REFCNT = 1 FLAGS = (PADMY,NOK,POK,pNOK,pPOK) IV = 0 NV = 0.01 PV = 0xa45c5c "hi"\0 CUR = 2 LEN = 10 dv2:hi 0.01 SV = PVNV(0x3f73c4) at 0xa8facc REFCNT = 1 FLAGS = (PADMY,NOK,POK,pIOK,pNOK,pPOK) IV = 0 NV = 0.01 PV = 0xa45c5c "hi"\0 CUR = 2 LEN = 10
