pyarrow.compute.shift_left_checked#
- pyarrow.compute.shift_left_checked(x,y,/,*,memory_pool=None)#
Left shiftx byy.
The shift operates as if on the two’s complement representation of the number.In other words, this is equivalent to multiplyingx by 2 to the powery,even if overflow occurs.An error is raised ify (the amount to shift by) is (1) negative or(2) greater than or equal to the precision ofx.See “shift_left” for a variant that doesn’t fail for an invalid shift amount.
- Parameters:
- xArray-like or scalar-like
Argument to compute function.
- yArray-like or scalar-like
Argument to compute function.
- memory_pool
pyarrow.MemoryPool, optional If not passed, will allocate memory from the default memory pool.
