NAME

Sah::Schemas::Float - Sah schemas for various floating types

VERSION

This document describes version 0.013 of Sah::Schemas::Float (from Perl distribution Sah-Schemas-Float), released on 2022-10-20.

SAH SCHEMAS

The following schemas are included in this distribution:

  • inf

    Inf or -Inf.

  • int_or_inf

    Integer, or Inf/-Inf.

  • nan

    NaN.

  • negfloat

    Negative float.

  • neginf

    -Inf.

  • percent

    A float.

    This type is basically float, with str_as_percent coerce rule. So the percent sign is optional, but the number is always interpreted as percent, e.g. "1" is interpreted as 1% (0.01).

    In general, instead of using this schema, I recommend just using the float type (which by default includes coercion rule to convert from percent notation e.g. '1%' -> 0.01). Use this schema if your argument really needs to be expressed in percents.

  • posfloat

    Positive float.

    See also ufloat for floats that are equal or larger than 0.

  • posinf

    Inf but not -Inf.

  • posint_or_posinf

    Positive integer, or Inf.

    Can be used to check value for number of items in a (possibly infinite) sequence.

  • share

    A float between 0 and 1.

    Accepted in one of these forms:

     0.5      # a normal float between 0 and 1
 10       # a float between 1 (exclusive) and 100, interpreted as percent
 10%      # a percentage string, between 0% and 100%

    Due to different interpretations, particularly "1" (some people might expect it to mean "0.01" or "1%") use of this type is discouraged. Use Sah::Schema::percent instead.

  • ufloat

    Non-negative float.

    See also posfloat for floats that are larger than 0.

  • uint_or_posinf

    Unsigned integer, or Inf.

    Can be used to check value for number of items in a (possibly infinite) sequence.

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.
