Re: Math 101 anyone?

[Crian]

I just tried out the behaviour of Perl in this case and found this:
perl -e "print 1/10"
gives the result 0.1

Also does
perl -e "print 1.0 / 10"
and
perl -e "print 1.0 / 10.0".

But
perl -e "print 100.1 - 100.0"
gives the well known 0.0999999999999943.

(All under ActiveStates Perl 5.8.0 under Windows 2000.)

Is there a special mechanism in Perl that "saves" the fraction? Or do I miss something else?

Try this:

printf "%.32f\n", 1/10;
0.10000000000000001000000000000000
