This standard bit-string function performs a bitwise left shift operation on the standard WORD operand connected to the IN input. N specifies the number of bits to be shifted.
The following rules apply:
The "empty bit positions" resulting from the shifting operation are filled with zeros.
When shifting with N < 0, the function delivers the output value 0 because the N parameter is considered as an unsigned integer value.
Example: bitwise left shifting with N = 3 bits.
