How does Perl conclude the results inf and NaN in the Bash session below? (The execution environment and Perl version are as displayed.) 

[[Bash command line prompt]] uname -s -r -v -m -o
CYGWIN_NT-6.1-WOW64 1.7.14(0.260/5/3) 2012-04-25 09:41 i686 Cygwin
[[Bash command line prompt]] perl -v | grep 'This is perl'
This is perl, v5.10.1 (*) built for i686-cygwin-thread-multi-64int
[[Bash command line prompt]] cat calc.pl
#!/usr/bin/perl -w
use strict;
use Math::BigFloat ':constant';
print "150 / 0.75 == ", 150 / 0.75, "\n";
print "(int(150.5)) / 0.75 == ", (int(150.5)) / 0.75, "\n";
print "150 / 3.75 == ", 150 / 3.75, "\n";
print "(int(150.5)) / 3.75 == ", (int(150.5)) / 3.75, "\n";
[[Bash command line prompt]] ./calc.pl
150 / 0.75 == 200
(int(150.5)) / 0.75 == inf
150 / 3.75 == 40
(int(150.5)) / 3.75 == NaN
