Does Perl formally support exponential notation for octal numbers? · Issue #18664 · Perl/perl5 · GitHub

Description

perldata does not mention a octal floating point form, but apparently it works:

$ perl5.32.0 -le 'print 01.4441766521041321410646114314242700334p+1'
3.14159265358979
$ perl5.33.8 -le 'print 0o1.4441766521041321410646114314242700334p+1'
3.14159265358979

Is this intended? If so, it should be added to the list of scalar value constructors.

If this is not intended, I guess it should stop doing that.
