bit.get
Function Retrieves the weighted 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.get(value1, index)
value1 Given number.
index Index position of the bit to be retrieved (1 to 32).
value Returned weighted value of the bit.
Remarks • This function returns the value of the bit in value1 at the given index. This is the same as
returning value1 with all other non-indexed bits set to zero.
• Prior to retrieving the indexed bit, any fractional part of the given number will be truncated to
make it an integer. The least significant bit of the given number has an index of 1 and the most
significant bit has an index of 32.
• If the indexed bit for the number is set to 0, the result will be 0.
•See Logic and bit operations for more information.
Also see bit.clear, bit.getfield, bit.set, bit.setfield, bit.test, bit.toggle
Example The binary equivalent of decimal 10 is 1010. Getting the bit at index position 4 will return decimal
value 8:
value = bit.get(10, 4)
print(value)
Output: 8.000000e+00
bit.getfield
Function Returns a field of bits starting at a given index position.
TSP-Link
accessibility
This function cannot be accessed from a remote TSP-Link node.
Usage value = bit.getfield(value1, index, width)
value1 Given number.
index Index position of the first bit; 1 to (33 – width).
width Field width – number of bits to be included in the
field; 1 to 24.
value Returned value of the bit field.
Remarks • A field of bits is a contiguous group of bits. This function retrieves a field of bits from value1
starting at the given index position. The index position is the least significant bit of the
retrieved field. The number of bits to return is given by width.
• Prior to retrieving the field of bits, any fractional part of the given number will be truncated to
make it an integer.
• The least significant bit of the given number has an index of 1 and the most significant bit has an
index of 32.
•See Logic and bit operations for more information.
Also see bit.clear, bit.get, bit.set, bit.setfield, bit.test, bit.toggle
Example The binary equivalent of decimal 13 is 1101. The field at index2 and width3 consists of the
binary bits 110. The returned value will be decimal 6 (binary 110):
value = bit.getfield(13, 2, 3)
print(value)
Output: 6.000000e+00
