; Converts a number into the name of the number
;
; The function Number2Name(Number) converts an integer from 1 to 999,999,999,999 into the name of the number.
; For example, the number 264358 converts to "two hundred sixty-four thousand three hundred and fifty eight".
; See http://en.wikipedia.org/wiki/List_of_numbers#Cardinal_numbers for reference. Comma separators in the
; number are allowed, e.g. 264,358.
;
; The function sets ErrorLevel to one of the following values:
;
;    0 - If the conversion was successful
;    1 - If the number contains any non-digit characters other than commas ("123.4")
;    2 - If the number is larger than the maximum (10**12-1)

; Convert the name of a number into the number
;
; The function Name2Number(String) converts the name of a number into a number from 1 to 999,999,999,999.
; For example, the string "two hundred sixty-four thousand three hundred and fifty eight" converts to 264358.
; See http://en.wikipedia.org/wiki/List_of_numbers#Cardinal_numbers for a reference to the names of numbers.
; Numbers such as "eleven hundred" are not allowed. Use "one thousand one hundred" instead.
; Spaces and tabs are allowed at the start and end of the string and in between words.
; Hyphenated ("twenty-one") and non-hyphenated names ("twenty one") are allowed.
; The word "and" can be used inside the string but only after the words hundred, thousand, million, or billion.
;
; The function sets ErrorLevel to one of the following values:
;
;    0 - If the conversion was successful
;    1 - If there are typos ("elevn") or spaces inside hyphenated ("twenty- one") or regular ("seven teen") words
;    2 - If there are syntax errors in the string ("two hundred thirty ten" or "one-thirty")
