bit.test
Function Returns the Boolean value (true or false) of a bit at a given index position.
TSP-Link
accessibility
This function cannot be accessed from a remote TSP-Link node.
Usage value = bit.test(value1, index)
value1 Given number.
index Index position of the bit to be tested (1 to 32).
value Returned decimal value of the bit.
Remarks • This function returns value, which is the result of the tested bit. The least significant bit of the
given number is at index 1. The most significant bit is at index 32.
• Any fractional part of value1 will be truncated to make it an integer. If the indexed bit for
value1 is set to 0, the returned value will be false. If the indexed bit for value1 is set to 1, the
returned value will be true.
• If the index is bigger than the number of bits in value1, the result will be false.
•See Logic and bit operations for more information.
Also see bit.clear, bit.get, bit.getfield, bit.set, bit.setfield, bit.toggle
Example The binary equivalent of decimal 10 is 1010. Testing the bit at index position 4 will return a Boolean
value of true:
value = bit.test(10, 4)
print(value)
Output: true
bit.toggle
Function Toggles the value of a bit at a given index position.
TSP-Link
accessibility
This function cannot be accessed from a remote TSP-Link node.
Usage value = bit.toggle(value1, index)
value1 Given number.
index Index position of the bit to be toggled (1 to 32).
value Returned value of the new number.
Remarks • This function returns value, which is the result of toggling a bit in value1.
• Any fractional part of value1 is truncated to make it an integer. The returned decimal value is
also an integer. The least significant bit of the given number is index 1. The most significant bit is
index 32.
• The indexed bit for value1 is toggled from 0 to 1, or 1 to 0.
•See Logic and bit operations for more information.
Also see bit.clear, bit.get, bit.getfield, bit.set, bit.setfield, bit.test
Example The binary equivalent of decimal 10 is 1010. Toggling the bit at index position 3 will return a decimal
value of 14 (binary 1110).
value = bit.toggle(10, 3)
print(value)
Output: 1.400000e+01
