I have these results from several languages all in Intel x86 machine

C++ std math.h cos(100000000.0): -0.363385
Java cos(100000000.0) :-0.3633850893556905
Perl cos (100000000.0):-0.36338508935581

why Perl is returning last digits wrong, and why it does not truncate it to what it knows it is the last precision it can correctly calculate?
