Remarks • This function performs a logical OR operation on two numbers.
• Any fractional parts of value1 and value2 are truncated to make them integers. The
returned value is also an integer.
•See “Logic and bit operations” on page 12-10 for more information.
Also see bit.bitand, bit.bitxor
Example OR’ing decimal 10 (binary 1010) with decimal 9 (binary 1001) will return a value of decimal
11 (binary 1011):
value = bit.bitor(10, 9)
print(value)
Output: 1.100000e+01
bit.bitxor
Function Performs a bitwise logical XOR (Exclusive OR) operation on two numbers.
Usage value = bit.xor(value1, value2)
value1 First number for the XOR operation.
value2 Second number for the XOR operation.
value Returned result of the XOR operation.
Remarks • This function performs a logical Exclusive OR operation on two numbers.
• Any fractional parts of value1 and value2 are truncated to make them integers. The
returned value is also an integer.
•See “Logic and bit operations” on page 12-10 for more information.
Also see bit.bitand, bit.bitor
Example XOR’ing decimal 10 (binary 1010) with decimal 9 (binary 1001) will return a value of
decimal 3 (binary 0011):
value = bit.bitxor(10, 9)
print(value)
Output: 3.000000e+00
bit.clear
Function Clears a bit at a given index position.
Usage value = bit.clear(value1, index)
value1 Given number.
index Index position of the bit to be cleared (1 to 32).
value Returns the result of the manipulation.
Remarks • This function clears a bit at a given index position.
• Any fractional part of value1 is truncated to make it an integer. The returned value is
also an integer.
• The least significant bit of the given number is at index 1. The most significant bit is at
index 32.
•See “Logic and bit operations” on page 12-10 for more information.
Also see bit.get, bit.getfield, bit.set, bit.setfield, bit.test, bit.toggle
Example The binary equivalent of decimal 15 is 1111. If you clear the bit at index position 2, the
returned decimal
value would be 13 (binary 1101):
value = bit.clear(15, 2)
print(value)
Output: 1.300000e+01
bit.get
Function Retrieves the weighted value of a bit at a given index position.
