1) CODE TITLE: Convert Numbers to Text

2) AUTHOR NAME/NOTES: Michael J. Hill www.javascript-demos.com

3) DESCRIPTION: For example, the code converts 1865, to One Thousand Eight Hundred Sixty Five. The range is -999,999,999 to 999,999,999. No range test is included, because you may want a different range than the maximum, and you may not want to support negative numbers. Commas, dollar signs, etc, are optional, and/or ignored.
