Error: log(xdouble): argument must be positive #415

Open naynajain opened 3 years ago

naynajain commented 3 years ago

Hi,

I am seeing following error: " log(xdouble): argument must be positive". I am also seeing this error - "double to xdouble conversion: non finite value".

I am seeing this error after many number of CT-CT mult, CT-CT additions are performed.

I am not able to figure out if it is a depth issue (value of L) or some other reason causing noise issue.

Any answer will be helpful.

Thanks & Regards,
