My apologies if this is a duplicate bug report. This is a bug report for perl from ovid@allaroundtheworld.fr, generated with the help of perlbug 1.40 running under perl 5.26.2. ----------------------------------------------------------------- [Please describe your issue here] Calling int() in a scalar with a floating point number causes the pIOK flag to be set. This has led to a bug in Types::Standard: https://rt.cpan.org/Public/Bug/Display.html?id=130411 I believe int() should be a pure function and not change the state of the scalar. The following illustrates the issue: $ perl -MDevel::Peek -E 'my $num = 3.14; Dump($num); int($num); Dump($num)' SV = NV(0x7fa846016d68) at 0x7fa846016d80 REFCNT = 1 FLAGS = (NOK,pNOK) NV = 3.14 SV = PVNV(0x7fa846001ab0) at 0x7fa846016d80 REFCNT = 1 FLAGS = (NOK,pIOK,pNOK) IV = 3 NV = 3.14 PV = 0 Best, Ovid [Please do not change anything below this line] ----------------------------------------------------------------- --- Flags: category=core severity=medium --- Site configuration information for perl 5.26.2: Configured by ovid at Wed Mar 27 14:08:04 CET 2019.
