I was trying to do : 
perl -e 'print 0100101."\n"'

[download]
As expected I got the decimal equivalent of octal as: 
32833

However, doing 
perl -e 'print 100101."\n"'

[download]
returned 
String found where operator expected at -e line 1, near "100101."\n""
        (Missing operator before "\n"?)
syntax error at -e line 1, near "100101."\n""
Execution of -e aborted due to compilation errors.

Any idea why this fuss about a zero? Not a burning problem or something. Just curious.
