 # Integer digits reverser

## World's simplest integer tool

This browser-based program rewrites the digits of an integer backwards and prints them in the output. You can enter any number of integers in the input and they can be mixed with other textual data. The integers will be reversed and returned in exactly the same place as in the input. Created by math nerds from team Browserling.
Integer digits reverser tool What is a integer digits reverser?
With this online application, you can reverse the digits in an integer. It changes the order of all digits so that the ending digits go to the beginning and the leading digits move to the end. For example, the integer 1234 turns into 4321. It also works with negative integers and the value -4516 becomes -6154. You can rearrange the digits of many integers at once and there are no input format requirements – you can enter integers as a neat sequence, they can be in a table as statistical data, or just text with numerical values in it. The symbols surrounding the integers will be preserved in the output and the integers will get reversed in-place. Integerabulous!
Integer digits reverser examples Click to use
Reverse a Bunch of Integers
In this example, we reverse three different integers. The first integer is positive, the second is also positive but with an explicit plus sign, and the third integer is negative with a minus sign. The signs remain unchanged in the output but all digits get rearranged in the reverse order.
987654321 +3492913 -1024
123456789 +3192943 -4201
Reverse Matrix Elements
This example rewrites all elements of an integer matrix backwards. The matrix has a size of 3 by 3 and contains nine three-digit integers. All matrix elements are overwritten in-place with their reversed values and the shape and size of the matrix doesn't change in the output.

711 697 884 206 172 867 431 575 933
Reverse Integers in Text
In the input of this example, we enter a text about a farmer and his animals. The program automatically finds all integers in the text and spells them back to front. Thus, in the output, we get the same text but with the animals' count values reversed. Notice that the number of cows was a symmetric palindrome so it didn't change.
A farmer had 12 dogs, 438 cats, 2788 rats, and 12321 cows.
A farmer had 21 dogs, 834 cats, 8872 rats, and 12321 cows.
