Note: You can select these operators from the MATH/Base menu. For an example using
each operator, refer to the Technical Reference module.
integer1 and integer2 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.
integer1 or integer2 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.
integer1 xor integer2 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.
