Comparing or Manipulating Bits The following operators and functions let you compare or manipulate bits in a binary number. You can enter an integer in any number base. Your entries are converted to binary automatically for the bitwise operation, and results are displayed according to the Base mode. Boolean Operations Operator with syntax not integer · integer Note: You can select these operators from the MATH/Base menu. For an example using each operator, refer to Appendix A in this book. integer1 and integer2 integer1 or integer2 integer1 xor integer2 Description Returns the one's complement, where each bit is flipped. Returns the two's complement, which is the one's complement + 1. In a bit-by-bit and comparison, the result is 1 if both bits are 1; otherwise, the result is 0. The returned value represents the bit results. In a bit-by-bit or comparison, the result is 1 if either bit is 1; the result is 0 only if both bits are 0. The returned value represents the bit results. In a bit-by-bit xor comparison, the result is 1 if either bit (but not both) is 1; the result is 0 if both bits are 0 or both bits are 1. The returned value represents the bit results. Suppose you enter: 0h7AC36 and 0h3D5F Internally, the hexadecimal integers are converted to a signed, 32-bit binary number. Then corresponding bits are compared. If Base mode = HEX: If Base mode = BIN: Note: If you enter an integer that is too large to be stored in a signed, 32-bit binary form, a symmetric modulo operation brings the value into the range (page 346). 0h7AC36 = 0b00000000000001111010110000110110 and and 0h3D5F = 0b00000000000000000011110101011111 0b00000000000000000010110000010110 = 0h2C16 Leading zeros are not shown in the result. The result is displayed according to the Base mode. Chapter 20: Number Bases 347
