If all you want to do is eliminate the lowest 4 bits, use (INT(A1/16))*16 ----- Original Message ----- From: Graham North To: Sent: Monday, February 07, 2000 7:40 am Subject: [OT] Binary bits in excel I have an A2D input (16 bits) currently being displayed on an excel spreadsheet. The bottom 4 bits are noisy. Does anyone have experience with excel on how to get rid of these 4 bits. (Just like 4* RRCF in .asm) Thanks, I am struggling with excel. Graham
