Integer Digit Decrementer

World's Simplest Integer Tool

This browser-based app decreases the value of individual digits in one or more integers. You can subtract a constant amount from all digits at once or use a subtraction pattern that subtracts a different amount from each digit. If a digit becomes less than 0, then you can control the underflow in the options. It can either be cyclically decremented to 9 or you can make it stop decrementing at 0. Created by math nerds from team Browserling.

Underflow Control

If the difference becomes
less than 0, then continue
subtracting from 9.

What Is an Integer Digit Decrementer?

With this web application, you can decrement digits of the given integer. The integer is modified in-place and the data that surrounds it isn't changed. To do its job, the program parses the text that you enter, finds and saves the positions of all integers in it, then decreases the digits in the found integers, and then puts them back in their original positions. There are two options that control how the digits get subtracted – "Decrease All Digits" and "Decrease Individual Digits". The first option subtracts the same value from each digit and you can enter this value below the option. The second option lets you subtract different amounts from the digits. For example, you can decrement only the last digit of an integer or every second digit. This option accepts a subtrahend pattern that specifies the amounts to be subtracted from tens, hundreds, thousands, tens of thousands, and so on. For example, if you enter the integer "987" in the input and set the pattern to "011", you will get "976" in the output (because only ones and tens decrease by 1). There are also two additional radio options that control the digit underflow. In the case when the difference drops below zero, you can leave the difference to be equal to zero by using the "Stop at 0" option or make it cyclically wrap to 9 by using the "Underflow to 9" option. For example, if the input integer is 23 and you subtract 4 from it, then with the first option, you will get the value 00 in the output because both 2-4 and 3-4 are less than 0 so both stop at 0, but with the second option you will get the value 89 in the output because as the differences 2-4 and 3-4 becomes less than 0, they switch from 0 to 9 and the subtraction continues. Integerabulous!

Decrease All Digits by One

In this example, we decrease the digits of two integers by 1. The first integer consists only of even digits, therefore subtracting 1 from each digit turns all even digits into odd digits. As we have activated the "Underflow to 9" option, the last digit 0 that is decreased by 1 becomes 9 because of the underflow. The second integer consists only of odd digits, therefore it becomes an integer of even digits in the output.

If the difference becomes
less than 0, then continue
subtracting from 9.

Subtract a Pattern

This example uses a nine-digit subtracting pattern "123456789" that is applied on a bunch of nine-digit integers. With this pattern, the digit at ones position is decreased by 9, the digit at tens position is decreased by 8, the digit at hundreds position is decreased by 3, …, and digit at hundred-millions position is decreased by 1. It also activates the underflow-to-9 option, which controls what happens if the result of subtraction is less than 0.

Simplify Statistical Data

In this example, we decided to simplify the website traffic statistics and round the last three digits of the number of visitors to zero. To quickly do it, we used a special digit decrement pattern "000999" together with the stop-at-zero option. This option prevents digits from underflowing to 9 and they stay at 0. Thus, in the output, we get rounded integer data with the lower half of the digits zeroed-out.
