Hello, when using your codebase, I found that the plaintext space is rather small, can you please guide me how to expand the plaintext space?

Hello, we have adjusted the parameters according to the lattigo library and modified the file, but the homomorphic multiplication of a large value (such as 100.0) still fails to get the correct result. The parameters we choose are as follows:

• PRIMES {0x4000000120001, 0x10000140001, 0xffffe80001}
• SPECIAL_PRIMES {0x40000001b0001, 0x3ffffffdf0001, 0x4000000270001}
• Parameters parametersEval((1ULL << 40), 32768, PRIMES, SPECIAL_PRIMES)

Is there any solution? I look forward to your reply.

Hi @taxuexunshang, I just saw this question. I think the value 100 is too big for that scale - did you try decreasing the scale?
