Numbers & Text

This is part of “An intro to Coding” series of posts, with content from the Enki app. If you stumbled upon this, you can start from the beginning.


Just as in maths, we can categorize numerical data based on their properties.

  • we can have whole, or integer numbers like 1, 999, -13
  • we can have fractional numbers or floats like 12.33, 0.0001, -13.2
  • we can even have complex numbers like 13 + 2j

In order to make everything easier and faster to work with, programming languages usually have different ways to store and interact with these types of numbers.

Let's define an integer!

💡 Depending on the programming language, you might have to type the data type before the variable name.


In the land of computers, the text type is almost never called text.

Instead, it is referred to as a string¹ (meaning a string of characters).

We've already seen this type before when creating the best_app variable.

Now, let's make another one:

💡 To help the computer distinguish strings from variable names, we wrap strings in quotes (" "). In some programming languages, you can also use single quotes (' ') and/or backticks (` `).
