pyarrow.compute.log1p_checked

pyarrow.compute.log1p_checked(x, /, *, memory_pool=None)

Compute natural log of (1+x).

Values <= -1 return -inf or NaN. Null values return null. This function may be more precise than log(1 + x) for x close to zero. Use function “log1p” if you want invalid values to return -inf or NaN.

Parameters:

xArray-like or scalar-like

Argument to compute function.

memory_poolpyarrow.MemoryPool, optional

If not passed, will allocate memory from the default memory pool.
