The
bit.bitand
,
bit.bitor
and
bit.bitxor
functions in this group perform logic operations on two
numbers. The TSP (Test Script Processor) will perform the indicated logic operation on the
binary equivalents of the two integers. Logic operations are performed bitwise. That is, Bit 1 of
the first number is AND'ed, OR'ed or XOR'ed with Bit 1 of the second number. Bit 2 of the first
number is AND'ed, OR'ed or XOR'ed with Bit 2 of the second number. This bitwise logic
operation is performed on all corresponding bits of the two numbers. The result of a logic
operation will be returned as an integer.
Bit operations:
The rest of the functions in this group are used for operations on the bits of a given number.
These functions can be used to clear a bit, toggle a bit, test a bit, set a bit (or bit field) and
retrieve the weighted value of a bit (or field value). All of these functions use an index parameter
to "point" to the bit position of the given number. The least significant bit of a given number has
an index of 1, and the most significant bit has an index of 32.
bit.bitand
Function
Performs a bitwise logical AND operation on two numbers.
Usage
value = bit.bitand(value1, value2)
value1
: First number for the AND operation.
value2
: Second number for the AND operation.
value
: Returned result of the AND operation.
Remarks
This function performs a logical AND operation on two numbers.
Any fractional parts of value1 and value2 are truncated to make them integers.
The returned value is also an integer.

Logic and bit operations
(on page 9-9)
Example
Adding decimal 10 (binary 1010) with decimal 9 (binary 1001) will return a value of
decimal 8 (binary 1000):
value = bit.bitand(10, 9)
print(value)
Output:
8.00
bit.bitor
Function
Performs a bitwise logical OR operation on two numbers.
Usage
value = bit.bitor(value1, value2)
value1
: First number for the OR operation.
value2
: Second number for the OR operation.
value
: Returned result of the OR operation.
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.
