pyarrow.compute.sign

pyarrow.compute.sign(x, *, memory_pool=None)

Get the signedness of the arguments element-wise.

Output is any of (-1,1) for nonzero inputs and 0 for zero input. NaN values return NaN. Integral values return signedness as Int8 and floating-point values return it with the same type as the input values.

Parameters

• x (Array-like or scalar-like) – Argument to compute function

• memory_pool (pyarrow.MemoryPool, optional) – If not passed, will allocate memory from the default memory pool.
