Menu label   LOGIC Menu Description Logical bit-by-bit "AND" of two arguments. For example: AND(1100b,1010b)=1000b Logical bit-by-bit "XOR" of two arguments. For example: XOR(1101b,1011b)=110b Logical bit-by-bit "OR" of two arguments. For example: OR(1100b,1010b)=1110b Returns the one's complement of the argument. Each bit in the result is the complement of the corresponding bit in the argument. For example: NOT(1011b)= 111111111111111111111111111111110100b Logical bit-by-bit "NAND" of two arguments. For example: NAND(1100b,1010b)=11111111111111111111111 1111111110111b Logical bit-by-bit "NOR" of two arguments. For example: NOR(1100b,1010b)= 111111111111111111111111111111110001b The "AND", "OR", "XOR", "NOT", "NAND", "NOR" can be used as logic functions. Fraction, complex, vector arguments will be seen as an in logic function. Arithmetic in Bases 2, 8, and 16 You can perform arithmetic operations using and  in any base. The only function keys that are actually deactivated in HEX mode are and . However, you should realize that most operations other than arithmetic will not produce meaningful results since the fractional parts of numbers are truncated. Arithmetic in bases 2, 8, and 16 is in 2's complement form and uses integers only: If a number has a fractional part, only the integer part is used for an arithmetic calculation. 11-4 Base Conversions and Arithmetic and Logic
