Numbers

You got "double" as an output in the last chapter, despite the number 10 being an integer. Let's investigate it.

What types can numeric values in R be? Let's remind. These are:

  • numeric/double - real numbers.
  • integer - integer numbers.
  • complex - complex numbers.

But in the last chapter, you got "double" for an integer number. How to make R recognize integer numbers? One of the ways is to simply put L at the end of the number. For example,

12
typeof(10) # Example of double type typeof(10L) # Example of integer type
copy

This script will return the next output:

python

Why do we even need to differentiate 10 and 10L values? The answer is memory consumption - storing integers is 'easier' for computer memory.

Tarefa

Swipe to start coding

  1. Assign the current year's value to the variable year. Make this variable integer type by using L.
  2. Output type of newly created variable year.
