Shifts x the number of bits specified by y.

The connector pane displays the default data types for this polymorphic function.

y can be any numeric representation. If y is greater than 0, the function shifts x left y bits (from least significant to most significant bit) and inserts zeros in the low-order bits. If y is less than 0, the function shifts x right y bits in the positive direction (from most significant to least significant bit) and inserts zeros in the high-order bits.
x can be any integer representation. If x is an 8-, 16-, 32-, or 64-bit integer and y is greater than 8, 16, or 32, or 64 or is less than –8, –16, –32, or –64, respectively, the output value is all zeros.
x << y is the result of the shift and has the same numeric representation as x.
