Beginning Perl book: NaN vs 0

In chapter 2, code string4.plx the output given for the code

Code:

#!/usr/bin/perl
#string4.plx
use warnings;
print "Ba". "na"x4*3, "\n";
print "Ba". "na"x(4*3), "\n";

is

Ba0
Banananananananananananana

but running this on Strawberry Perl 5.22.2 for Windows 10 gives

BaNaN
Banananananananananananana

What's changed from the Perl point of view?
