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

With American formatting (default) Number::Spell should work for integers to

        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 
        hundred ninety nine quindecillion nine hundred ninety nine 
        quattuordecillion nine hundred ninety nine tredecillion nine hundred

        hundred ninety nine quadrillion nine hundred ninety nine trillion nine 
        hundred ninety nine billion nine hundred ninety nine million nine 
        hundred ninety nine thousand nine hundred ninety nine

and in European formatting mode is should be valid up-to
