# Disable Scientific Notation in R (2 Examples) | How to Prevent Exponential Numbers

In this tutorial, you will learn how to **disable scientific notation** (e.g. e+10) in the R programming language. The article will be structured as follows:

- Creation of Example Data
- Disable Scientific Notation with R Options (Example 1)
- Disable Scientific Notation with format Function (Example 2)
- Further Resources for the Handling of Exponential Notation in R

Figure 1 shows a **quick overview** of the following examples:

**Figure 1: Overview of Number Representations in R.**

However, for further explanations keep on readingâ€¦

## Create Example Data

In the examples of this article, I will use the following numeric data object:

x <- 123456789101112131415 # Example data object x # Print example data to console # 1.234568e+20

We will use the number 123456789101112131415, which is stored in the data object x.

As you can see based on the previous RStudio console output, base R formats this number automatically to an **exponential notation** (i.e. 1.234568e+20).

In the following examples, I will show you two ways how to disable this notation in R.

So without further ado, letâ€™s move on to the examplesâ€¦

## Example 1: Modify R Options to Disable Scientific Notation

A general approach is to change the options within R. You just need to execute the following syntax in order to tell R that it should not show scientific notation anymore:

options(scipen = 999) # Modify global options in R

Letâ€™s see what happens when we print our example data to the RStudio console again:

x # Print example data once more # 123456789101112131415

The exponential representation was removed and all digits are shown.

Keep in mind that R does not store very large numbers “precisely”, so for that reason, the numbers shown in the output differ from our example data object. You can find more on this here.

**Note:** With the previous code, we changed the general R settings. If you want to move back to the old settings you can either restart RStudio; Or you can back up the default options before changing them; Orâ€¦

â€¦you might use the syntax shown in the next example, where we switch off scientific notation for only one specific number!

## Example 2: Disable Scientific Notation with the format R Function

The R format function enables us to prevent R from showing an exponential representation. Have a look at the following R code:

format(x, scientific = FALSE) # Apply format function in R # "123456789101112131584"

As you can see, the whole number with all digits was returned to the RStudio console.

**Note:** This number was converted to the character class. If you want to perform calculations with the converted output, you need to transform this character back to numeric.
