Notes on Letter Cases used to write out in words the number above:

1: Lowercase: only lowercase letters are used. Example: 'seventy-six and two tenths'.


2: Uppercase: only uppercase letters are used. Example: 'SEVENTY-SIX AND TWO TENTHS'.


3. Title Case: first letter of each word is capitalized, except for certain short words, such as articles, conjunctions and short prepositions, 'a', 'an', 'the', 'and', 'but', 'for', 'at', 'by', 'to', 'or', 'in', etc. Example: 'Seventy-Six and Two Tenths'.


4. Sentence case: only the first letter of the first word is capitalized. Example: 'Seventy-six and two tenths'.


5. Start Case: first letter of each word is capitalized without exception. Example: 'Seventy-Six And Two Tenths'.


6. Camel Case: text has no spaces nor punctuation and first letter of each word is capitalized except for the very first letter in the series. Example: 'seventySixAndTwoTenths'.

Pascal Case: See the Camel Case above, but the first letter is also capitalized. Example: 'SeventySixAndTwoTenths'.


7. Hyphen Case: text has no spaces nor punctuation and the words are delimited by hyphen. Example: 'seventy-six-and-two-tenths'. Hyphen Case can be lowercase or uppercase.


8. Snake Case: text has no spaces nor punctuation and the words are delimited by underscore. Example: 'seventy_six_and_two_tenths'. Snake Case can be lowercase or uppercase.


Notes on Writing Out Numbers:

1: It's correct to hyphenate all compound numbers from twenty-one (21) through ninety-nine (99). The hyphen is the minus sign, as in 'thirty-four' (34).


2: In American English, unlike British English, when writing out natural numbers of three or more digits, the word 'and' is not used after 'hundred' or 'thousand': so it is 'one thousand two hundred thirty-four' and not 'one thousand two hundred and thirty-four'.


3. Do not use commas when writing out in words numbers above 999: so it is 'one thousand two hundred thirty-four' and not 'one thousand, two hundred thirty-four'.


4. Use commas when writing in digits numbers above 999: 1,234; 43,290, etc.

How to convert ordinal numerals to words in (US) American English, how to write them out using letters instead of numerals

How to write out ordinal numbers (those denoting order) in words?

Most ordinal numbers end in "th", so just add "th" to the end of the cardinal number (those denoting quantity, ex: 1 one, 2 two, 3 three, 4 four, ... etc.):

  • cardinal: 4 = four -> ordinal: 4th = fourth
  • cardinal: 7 = seven -> ordinal: 7th = seventh
  • cardinal: 10 = ten -> ordinal: 10th = tenth
  • cardinal: 19 = nineteen -> ordinal: 19th = nineteenth
  • cardinal: 100 = one hundred -> ordinal: 100th = (one) hundredth
  • cardinal: 1,000 = one thousand -> ordinal: 1,000th = (one) thousandth

Exceptions:

  • cardinal: 1 = one -> ordinal: first = 1st
  • cardinal: 2 = two -> ordinal: second = 2nd
  • cardinal: 3 = three -> ordinal: third = 3rd
  • cardinal: 5 = five -> ordinal: fifth = 5th
  • cardinal: 8 = eight -> ordinal: eighth = 8th
  • cardinal: 9 = nine -> ordinal: ninth = 9th
  • cardinal: 12 = twelve -> ordinal: twelfth = 12th
  • cardinal: 20 = twenty -> ordinal: twentieth = 20th
  • cardinal: 30 = thirty -> ordinal: thirtieth = 30th
  • cardinal: 40 = forty -> ordinal: fortieth = 40th
  • cardinal: 50 = fifty -> ordinal: fiftieth = 50th
  • cardinal: 60 = sixty -> ordinal: sixtieth = 60th
  • cardinal: 70 = seventy -> ordinal: seventieth = 70th
  • cardinal: 80 = eighty -> ordinal: eightieth = 80th
  • cardinal: 90 = ninety -> ordinal: ninetieth = 90th
