11-4 Base Conversions and Arithmetic and Logic

LOGIC Menu

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.

Menu label 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
