T TsAmE New Member Mar 15, 2011 #1 Convert 0110.01110101 (8421 BCD) to binary The only thing that I know is that 8421 BCD represents the numbers 0..9. What would be the procedure to do this calculation?

MikeMl Well-Known Member Most Helpful Member Mar 15, 2011 #2 Presumably, 0110.01110101 should be written 0110/0111/0101, where each group of four represents a decimal digit? X = 0110b = 2^2 + 2^1 = 6 I'll let you do these: Y = 0111b = ? Z = 0101b = ? So the decimal value is D = 100X +10Y + Z = ? Now convert D to binary.
