NAME

Number::Spell - Perl extension for spelling out numbers

SYNOPSIS

  use Number::Spell;
  my $str=spell_number(519252);

DESCRIPTION

Number::Spell provides functionality for spelling out numbers. Currently only integers are supported.

By default Number::Spell does American formatting, but can be configured to do European formatting by calling it with the ``Format => 'eu''' option:

        spell_number( ...  , Format => 'eu');

American and European formatting differ in how they represent numbers one billion and above.

        number          :       20000000000 (2 * 10^11)
        American format :       twenty billion
        European format :       twenty thousand million

        nine hundred ninety nine vigintillion nine hundred ninety nine
        novemdecillion nine hundred ninety nine octodecillion nine hundred
        ninety nine septendecillion nine hundred ninety nine sexdecillion nine
