Reference : https://www.programmingsimplified.co...reversenumber Is it possible to write a computer program which will reverse a decimal or floating point number? Example : 341.54 Output : 45.143 Do we have to just change the data type to float or double instead of int in the above C program reference or the programming logic has to be also modified?

Yes you could easily store each digit of a number in a vector and then just flip it and put the digits back together.

Thank you. Can you please send me the computer program in C , C++ , Java , C# & Python programming languages ? I will compile with the respective compilers and run the program in the respective SDK. Once again , thank you. Thanks & Regards, Prashant S Akerkar Last edited by akerkarprashant; November 2nd, 2018 at 12:43 AM. Reason: Content.

The art of programming is to pick the language to suit the application. There's no point in writing something so basic in so many languages unless you are doing it for practice.

Thanks. https://perlmaven.com/reverse As you mentioned in Perl code, the scalar function is called which could be the inbuilt function in the Perl math or string library. Can you give me the source code of the scalar function? This is required to know the algorithm or programming logic for giving us the reverse of a floating or decimal point number. As you see, https://www.programmingsimplified.co...reversenumber There is a source code for reverse of a Integer data type. Similarly, Can we have the source code of a reverse of a floating or decimal point number? Thanks, once again.

Reversing a floating point number isn't properly defined in the question. The example reverses a number given in decimal form, not floating point form.

The scalar function forces the reverse function to treat the input as a string rather than as an element of an array.
