Formal Ways to Say a Number in Integer

When using formal language, it’s important to adhere to certain guidelines to ensure clarity and precision in your communications. Here are some tips for expressing numbers as integers formally:

  1. Use plain language: When communicating numbers in a formal setting, it’s best to avoid using abbreviations or slang. Instead, use complete words to express the number clearly.
  2. Spell out smaller numbers: For integers between zero and ten, it is customary to spell them out in formal writing. For larger numbers, the numerical representation is generally preferred.
  3. Use commas to separate thousands: When expressing larger integers in formal writing, it is common practice to use commas to separate thousands. For example, “6,000” instead of “6000.”

Let’s take a look at some examples to illustrate formal ways of expressing numbers:

Example 1:

The project’s budget is twenty-seven million dollars.

Example 2:

The event attracted approximately 5,000 attendees.

Informal Ways to Say a Number in Integer

Informal language allows for a more relaxed and casual approach to expressing numbers as integers. However, it’s still important to maintain clarity and avoid confusion. These tips will help you express numbers informally:

  1. Use contractions: Informal language often incorporates contractions, such as “can’t” instead of “cannot,” to make conversation more conversational and friendly.
  2. Speak in approximate terms: Informally, you can round numbers to make them easier to communicate. Instead of stating an exact figure, you can use approximations like “around,” “about,” or “approximately.”
  3. Drop unnecessary zeros: When expressing numbers informally, it is acceptable to drop unnecessary zeros after the decimal point. For example, saying “2.5” instead of “2.500.”

Let’s see some examples of how to express numbers informally:

Example 1:

He’s gotta be in his forties by now.

Example 2:

There were maybe a couple hundred people at the concert.

Regional Variations

Though the basic principles of expressing numbers as integers are quite universal, there may be some regional variations in how numbers are formatted or spoken. Here are a few examples:

  1. British English: In British English, the word “and” is often used before the last two digits of a whole number or decimal. For instance, “one hundred and fifty-five” instead of “one hundred fifty-five.”
  2. Indian English: In Indian English, numbering systems can differ slightly from their Western counterparts. For example, “one lakh” is equal to one hundred thousand.

Keep in mind that these regional variations are not exhaustive, but rather, a glimpse into the diverse ways numbers can be expressed across cultures.


Whether you’re aiming for a formal or informal tone, expressing numbers as integers can be straightforward once you understand the basic guidelines. Remember to adjust your language and level of formality based on the context, and consider any regional variations that may exist. By following these tips and examples, you’ll be able to comfortably navigate conversations or written communications where numbers are the topic. Happy number stating!
