Bad handling of small fractional numeric versions

[haarg]

If a version number is passed in numeric form, C::M::R will use its stringified form for all its processing. This doesn't play well with small fractional versions like 0.000005, which will be stringified as '5e-06', and thus rejected as invalid. For values that are numeric (possibly checked via looks_like_number or B flags) it should stringify them using sprintf '%f' instead.

version.pm already contains logic to handle that, I suspect that would be the most logical route.

The problem seems to be a bit more subtle. This is accepted:
PREREQ_PM
{
'Try::Tiny' => 0.09, # Fake V for testing.
}
but this:
TEST_REQUIRES =>
{
'Test2::Bundle::Extended' => 0.09,
}
produces the error:
Unparsable version '3e-05' for prerequisite Test2::Bundle::Extended treated as 3 at /home/ron/perl5/perlbrew/perls/perl-5.20.2/lib/site_perl/5.20.2/CPAN/Meta/Requirements.pm line 140.

Since the version # for Try::Tiny is faked, that of course produces a separate warning, but I assume by the time this warning:
Unparsable version '3e-05' for prerequisite Test2::Bundle::Extended treated as 3 at /home/ron/perl5/perlbrew/perls/perl-5.20.2/lib/site_perl/5.20.2/CPAN/Meta/Requirements.pm line 140.
is produced, what's happened is that your module is somehow handling the version #s in the 2 categories differently.

I found that by doing this:
'Test2::Bundle::Extended' => '0.000030',
everything worked as expected.
And no, I do not have to quote 'Try::Tiny' => 0.09.
