Does encryptBatch support fixed point number? #95

Closed ziyao002 closed 3 years ago

ziyao002 commented 3 years ago

Hi noticed that encodeBatch and encryptBatch can be used for integers, I was wondering if these two functions support fixed-point numbers (fractional numbers)? Besides, which FHE scheme used as the building block of Pyfhel? BFV or CKKS? Thank you so much in advance!

I'm afraid they don't. The FHE scheme implemented so far is a BFV variant (hence the lack of fixed-point support). CKKS support was envisioned, but I never found the time to include it.

Understand, thank you!

CKKS support is coming! stay tuned, as in less than 1 month we should have it here.
