Description Valid range
In
Data to
rotate
Input
The original data to rotate
left
Depends on the data type of the
variable that the input parameter is
connected to.
Num
Number of
bits
Input
The number of bits by
which the bits of the
original data are rotated
to the left
Depends on the data type of the
variable that the input parameter is
connected to.
Out Result Output
Result from rotating all
bits of the original data by
the number of bits
specified by Num to the
left
Depends on the data type of the
variable that the output parameter is
connected to.
