# Integer digit remover

World's simplest integer tool
This online utility removes certain digits from an integer and returns a modified integer without these digits in the output. You can specify which digits you want to delete and apply the deletion algorithm to any number of integers (one per line). By default, the algorithm deletes all occurrences of the specified digits but you can also use an option to delete just the first occurrence of each digit.

Digits to Remove
List all the digits you want to remove without delimiters. For example, "0123".
Removal Options
Remove only the first occurrence of a digit in an integer.
Remove first digit from the beginning.
Remove first digit from the end.

## What is a integer digit remover?

With this online application, you can delete the digits that you don't like from an integer. For example, you can make an integer contain only the odd digits 13579 by deleting the even digits 02468, or if you want to make sure that all the digits in an integer are greater than 4, you can remove the digits 01234, which will leave only the digits 56789 in the output. The unnecessary digits that you want to get rid of can be entered in the "Digits to Remove" option. This option accepts a list of digits in any order that should be entered without the space separators. The program then runs through all the input integers (each value should be on a new line) and outputs modified integers that contain only the digits that aren't listed in the "Digits to Remove" option. If you need to remove only the first occurrence of the listed digits, then use the "Delete Only the First Digit" option. In addition to this option, there are two side selection radio boxes. One of them removes the first digit from the left side and the other from the right side. Integerabulous!

## Integer digit remover examples

Click to use
Secret Integer
In this example, we reveal a secret integer that's composed of the digits 1 to 5 but that has been mixed with digits 6 to 9 and 0. It would be tricky to manually find the hidden integer but by quickly removing the digits 67890, we find that the secret integer is 12345.

List all the digits you want to remove without delimiters. For example, "0123".
Remove only the first occurrence of a digit in an integer.
Single Digit Removal
This example loads three integers that have been left-padded with a leading zero. The padding doesn't change the integers' value so we'd like to delete it. To remove the zero that's in front, we enter 0 in the removal list and set the option to delete only the first zero. This way, all other zeros in the integer are preserved.

Cleanup Binary Integers
In this example, the binary communication channel between two devices was noisy and the received binary data had many errors introduced during the transmission. To clean up the errors, we entered the non-binary digits 23456789 in the cleanup list, which let us extract only the binary integers 0 and 1, and the data was recovered.
