Hi everyone,

I used to think that as long as the “CurrentMultiplicativeDepth” is less than or equal to the “MaxMultiplicativeDepth,” multiplication would proceed without issues.

However, in a recent project, I set the “MaxMultiplicativeDepth” using `parameters.SetMultiplicativeDepth(8)`

, and the current “MultiplicativeDepth” of the ciphertext is 8. When I call `Decrypt()`

, I encounter the following error:

`openfhe-development/src/pke/lib/encoding/ckkspackedencoding.cpp:l.541:Decode(): The decryption failed because the approximation error is too high. Check the parameters.`

Can anyone advise on how to estimate the approximation error and ensure the program runs smoothly?

Thank you!
