NAME
Unicode::Number - handle numerals in Unicode using the libuninum library
VERSION
version 0.009
SYNOPSIS
use Unicode::Number;
my $u = Unicode::Number->new;
my $lao_str = "\x{0ED5}\x{0ED7}\x{0ED6}";
my $ns = $u->guess_number_system($lao_str);
say $u->string_to_number($ns, $lao_str)->to_string; # 576DESCRIPTION
This class is used to interface with the libuninum library to convert to and from different number system representations. It can be used to convert from a UTF-8 string to one of the types supported by Unicode::Number::Result.
METHODS
new
new()
Returns a new instance of Unicode::Number.
number_systems
number_systems()
Returns an arrayref of Unicode::Number::System instances.
get_number_system_by_name
get_number_system_by_name($name)
Returns the Unicode::Number::System that has the name given by the $name parameter (string) or undef if not found.
string_to_number
string_to_number($number_system, $digits_string)
Returns a Unicode::Number::Result that contains the results of converting the string given in the $digits_string parameter to a number in the number system represented by the $number_system parameter.
The value of $number_system can either be a Unicode::Number::System instance or a string (see get_number_system_by_name.)
The value of $digits_string must be encoded in UTF-8.
number_to_string
number_to_string($number_system, $number)
Returns a UTF-8 encoded string that represents the value of $number in the number system represented by $number_system.
The value of $number_system can either be a Unicode::Number::System instance or a string (see get_number_system_by_name.)
The value of $number can be either a numeric integer value or a string that matches the regular expression /[0-9]+/.
guess_number_system
guess_number_system($digits_string)
Returns the Unicode::Number::System that matches the contents of the numbers in the string $digits_string if it can be found.
In the special case when $digits_string contains only '0', then it returns a Unicode::Number::System with the name 'All_Zero' because several number systems make overlapping use of this glyph.
Otherwise, if the number system is unknown, returns undef.
The value of $digits_string must be encoded in UTF-8.
version
version()
Returns a string with the version of the libuninum library.
