FUNCTIONS

num

Usage:

num(%args) -> [$status_code, $reason, $payload, \%result_meta]

Format number.

Observe locale environment variable settings.

Undef and non-numbers are ignored.

This function is not exported.

Arguments ('*' denotes required arguments):

  • decimal_digits => int

    Number of digits to the right of decimal point.

  • in => array

    Input stream (e.g. array or filehandle).

  • out => any

    Output stream (e.g. array or filehandle).

  • prefix => str

    Add some string at the beginning (e.g. for currency).

  • style => str (default: "general")

    Available styles:

    • fixed (Fixed number of decimal digits, e.g. 1.00, default decimal digits=2)

    • general (General formatting, e.g. 1, 2.345)

    • kibi (Use Ki/Mi/GiB/etc suffix with base-10 [1000], e.g. 1.2Mi)

    • kilo (Use K/M/G/etc suffix with base-2, e.g. 1.2M)

    • percent (Percentage, e.g. 10.00%)

    • scientific (Scientific notation, e.g. 1.23e+21)

  • suffix => str

    Add some string at the end (e.g. for unit).

  • thousands_sep => str

    Use a custom thousand separator character.

    Default is from locale (e.g. dot "." for en_US, etc).

    Use empty string "" if you want to disable printing thousands separator.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)

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.
