;Task:
Show how to spell out a number in English.
You can use a preexisting implementation or roll your own, but you should support inputs up to at least one million (or the maximum value of your language's default bounded integer type, if that's less).
Support for inputs other than positive integers (like zero, negative integers, and floating-point numbers) is optional.
;Related task:
* [[Spelling of ordinal numbers]].

=={{header|AppleScript}}==
With AppleScript's ability to access some of macOS's Objective-C frameworks, it's possible to get the job done with a single line:
<syntaxhighlight lang="applescript">use AppleScript version "2.4" -- OS X 10.10 (Yosemite) or later
use framework "Foundation"
on numberToWords(n)
return (current application's class "NSNumberFormatter"'s localizedStringFromNumber:(n) numberStyle:(current application's NSNumberFormatterSpellOutStyle)) as text
end numberToWords
numberToWords(-3.6028797018963E+10)
--> "minus thirty-six billion twenty-eight million seven hundred ninety-seven thousand eighteen point nine six three"</syntaxhighlight>
NSNumberFormatter supports several natural languages and by default uses the one set for the user on the host machine. However, its English is limited to US English, so there are no "and"s in the results.
Vanilla AppleScript can be more flexible if you're prepared to write the code. The script below, like the ASObjC one above, returns short-scale number names, but includes "and"s by default. An optional parameter <code>without ands</code> can be added to the call if the "and"s are not wanted. Another optional parameter, <code>with longScale</code>, gets a British-English long-scale result, while a third, <code>with milliards</code>, gets a long-scale result with "milliard", "billiard", ''etc.'' between the "-illion"s instead of "thousand".
Both scripts can display strange results with numbers at the extreme limits of floating-point resolution.
<syntaxhighlight lang="applescript">-- Parameters:

=={{header|Commodore BASIC}}==
After adapting the Applesoft BASIC version to the Commodore, it became apparent there were serious rounding issues on larger numbers. (For example, 9,876,543,210 came up as nine billion eight hundred seventy-six million five hundred forty-three thousand two hundred twelve.) Other numbers were off by hundreds.
This example uses string variable to process the number rather than using integer or float processes. This should work on other 8-bit machines if adapted properly for their unique features and BASIC command sets.
'''Machine specific notes for the word wrap feature:'''
Set <tt>'''co'''</tt> on line 20 for the following Commodore machines:
* VIC-20: <tt>co=21</tt>.
* Commodore 64 or Plus 4: No change.
* PET: <tt>co=peek(213)</tt>. (Will detect 40 or 80 column mode.)
* CBM-II variants: <tt>co=peek(223)</tt>. (Will detect 40 or 80 column mode.)
* Commodore 128: <tt>co=rwindow(2)-1</tt>. (Will detect 40 or 80 column mode.)

The code for this solution became somewhat cumbersome as I worked to fine tune the output, so it might benefit from some hindsight refactoring. By default the function <tt>num2text</tt> names integers according to the Anglo-American short-scale convention and is limited to numbers less than 10^66. Optionally, integers can be named according to the Continental long-scale convention, in which case the limit is 10^126. In either case, one can spell out any of Julia's fixed-bit format integers. When these limits are exceeded the function returns "too big to say". 0 is treated as a special case, and negative integers are handled by pre-pending "minus" to the output of the corresponding positive integer.

Fraction ideas copied from [[Number_names#HicEst|HicEst]], using billion=10^9, trillion=10^12, quadrillion=10^15, and limited to 999 quadrillion.<br>
Implemented as an [[Executable_library]] for use in [[Names_to_numbers#Phix|Names_to_numbers]].<br>
The distribution now contains builtins\ordinal.e which implements spell() as ordinal(atom n, bool bJustSpell=true), see the manual.

.SYNOPSIS
Spells out a number in English.
.DESCRIPTION
Spells out a number in English in the range of 0 to 999,999,999.
.NOTES
The code for this function was copied (almost word for word) from the C#
example on this page to show how similar Powershell is to C#.
.PARAMETER Number
One or more integers in the range of 0 to 999,999,999.
.EXAMPLE
Get-NumberName -Number 666
