Have added a new error to make the INCRBYFLOAT command consistent with redis.

	ErrInvalidFloat               = errors.New("ERR value is not a valid float")                                         // Signals that a value provided is not in a valid float format.

Have also added documentation for INCRBY and INCRBYFLOAT commands as well.

Thanks

Hi @pg30 , I have checked the changes as per the checklist. I see that we are still having tests in async folder. We can migrate them to resp folder, (please use any existing test file in resp folder as reference). Additionally, we need to add tests in websocket folder too.

I will look at the changes thoroughly once it checks off everything and is ready for review.

Thanks

hi @pg30 you can use ErrGeneral for the error if it's not getting used at multiple evals, no need to create a separate error for this usecase. Thanks

@AshwinKul28 can you review this pls

@AshwinKul28 Http and Websockets integration tests in the PR involving big integers like math.MaxInt64 and math.MinInt64 are functionally working but not logically correct due to #1163 .
Can create a separate issue to clean up those once we fix it.

Hey @pg30 Thanks a lot for this commendable effort. Changes looks good. Please verify all the docs changes once whether they are aligned with the ideal document - https://github.com/DiceDB/dice/blob/master/docs/sample_command_docs.md

You can include best practices, and additional notes if required in each of these docs.

Otherwise, the changes look great. Once docs changes are confirmed will merge the PR.

@AshwinKul28 Thanks for reviewing the changes. I have added alternatives section for the INCR and DECR commands. Rest of the docs looks good to me. Feel free to merge the PR
