FUNCTIONS

None exported by default but all of them exportable.

format_metric($num, \%opts) => STR

Format $num using metric prefix. Locale settings are respected (this module uses locale). Might produce non-Latin Unicode characters (e.g. μ for 1e-6 prefix). Known options:

  • base => INT (either 2 or 10, default: 2)

  • precision => INT

  • i_mark => BOOL (default: 1)

    Give "i" suffix to prefixes when in base 10 for k, M, G, T, and so on.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
