Name of a Number input examples

There are a number of options available:

• The number given may be negative or positive.

  For example: 23209 or -391581216193

• Both whole and ``floating point'' numbers are allowed.

  For example: 21701 or 2.7182818284590452353602874713526624

• Scientific notation is allowed

  For example: 6.023e23 or -6.6260755e-34

  NOTE: Scientific notation is not allowed when raising 10 to a power. It is allowed for Latin powers (1000^x).

• One may ask for just the name of a power of 10 or a Latin power

  The first radio option controls how the value of the number is interpreted:

  Type of input:     Just a number Power of 10 Latin power (1000^number)

  By default, the name of the input value is processed.

  If the Power of 10 option is used, 10 is raised to the power of the input value.
  For example:

  Input: 13 (i.e., 10¹³)
  
  American decimal: 10,000,000,000,000
  European decimal: 10.000.000.000.000
  American system name: ten trillion
  European system name: ten billion

  If the Latin power option is used, then 1000 is raised to power of the input value.
  For example:

  Input: 7 (i.e., 1000⁷)
  
  American decimal: 1,000,000,000,000,000,000,000
  European decimal: 1.000.000.000.000.000.000.000
  
  
  American system name: one sextillion
  European system name: one trilliard

• The name produced may be from either the American or European system.

  There are at least two main English language based naming methods: American and European number systems. The American and European number systems also differ on how decimal numbers are displayed.

  1024	8	septillion	quadrillion
  1027	9	octillion	quadrilliard
  1030	10	nonillion	quintillion
  1033	11	decillion	quintilliard

  Naming system decimal notation

  System	Decimal	Group of 3	Example
  American	Decimal point	Group of 3 comma	391,581.216193
  European	Decimal comma	Group of 3 point	391.581,216193

• The number may be of almost any length.

  Over the web, we limit the size of the output because some numbers are really really big :-).

  If the size limit is a problem, you can download the source and save it without a .cgi filename extension. In this form it runs as normal program without all of the CGI/HTML processing. In normal program mode, the program does not enforce an arbitrary size limit.

  For more information see the number home page.
