NAME

Data::Sah::Filter::perl::Float::check_int - Check that a floating point number is integer

VERSION

This document describes version 0.025 of Data::Sah::Filter::perl::Float::check_int (from Perl distribution Data-Sah-Filter), released on 2024-07-17.

SYNOPSIS

Using in Sah schema's "prefilters" (or "postfilters") clause

 ["str","prefilters",[["Float::check_int"]]]

Using with Data::Sah:

 use Data::Sah qw(gen_validator);
 
 my $schema = ["str","prefilters",[["Float::check_int"]]];
 my $validator = gen_validator($schema);
 if ($validator->($some_data)) { print 'Valid!' }

Using with Data::Sah:Filter directly:

 use Data::Sah::Filter qw(gen_filter);
 my $filter = gen_filter([["Float::check_int"]]);
 # $errmsg will be empty/undef when filtering succeeds
 my ($errmsg, $filtered_value) = $filter->($some_data);

Sample data and filtering results

 1 # valid, unchanged
 -1.1 # INVALID (Number must be an integer), unchanged
 1.1 # INVALID (Number must be an integer), unchanged

DESCRIPTION

This filter checks that number is an integer, i.e. 2.5 fails but 2 succeeds.

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.
