pyarrow.compute.shift_left_checked(x, y, /, *, memory_pool=None)#

Left shift x by y.

The shift operates as if on the two’s complement representation of the number. In other words, this is equivalent to multiplying x by 2 to the power y, even if overflow occurs. An error is raised if y (the amount to shift by) is (1) negative or (2) greater than or equal to the precision of x. See “shift_left” for a variant that doesn’t fail for an invalid shift amount.
