[jira] [Commented] (NUMBERS-198) New function - reverse the digits of a number

["Gilles Sadowski (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NUMBERS-198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17742934#comment-17742934 ] 

Gilles Sadowski commented on NUMBERS-198:
-----------------------------------------

[~dimitrios.efthymiou],

How about taking it from the other end?
Rather than try and find a "small feature" (if it were in scope, how likely that it had not been implemented yet?), you could
* start a discussion about a missing functionality (e.g. "special" functions)
* select some bugs to fix (plenty on JIRA)
* take on some identified need (e.g. refactor the "clustering" package)

> I propose a new function for ArithmeticUtils that takes a number and it returns the number with the reversed digits. Some use cases are:
>  # *Palindrome Checking:* The algorithm can be used as a part of a function to check if a number is a palindrome (a number that remains the same when its digits are reversed).
>  # *Data Manipulation:* This algorithm could be used in a data manipulation or data cleaning process. For instance, in a situation where the digit order of numerical data has been systematically recorded incorrectly, this algorithm could be used to correct the data.
>  # *User Interface (UI) Design:* In cases where the presentation of numbers needs to be manipulated for display purposes, this could be useful. For instance, if a UI design decision prefers displaying digits in a reverse order.
>  # *Digital Signal Processing:* The bit-reversal operation is a crucial part of certain algorithms, such as the Fast Fourier Transform (FFT). Although the current method works with integers, a similar algorithm could be used for bit-reversal operations.
>  # *Cryptographic or Security Methods:* This method might be used as part of a larger algorithm in cryptography or security. However, this by itself does not provide any significant security benefits.
