Title: Pad stringification of exponent on systems that always use more than 2 digits

Perl builds on windows default to using *printf from Microsoft's MSVCRT. Microsoft chose a default of three digit exponents rather than the 2 digit ISO-C99 standard with the %e or %E conversion specifiers for doubles.

Check if a '0' generates an exponent longer that two digits and pad the expected test output strings appropriate.
