+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.

+    .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
