pyarrow.compute.round

pyarrow.compute.round(x, /, ndigits=0, round_mode='half_to_even', *, options=None, memory_pool=None)

Round to a given precision.

Options are used to control the number of digits and rounding mode. Default behavior is to round to the nearest integer and use half-to-even rule to break ties.

Parameters:

xArray-like or scalar-like

Argument to compute function.

ndigitsint, default 0

Number of fractional digits to round to.

round_modestr, default “half_to_even”

Rounding and tie-breaking mode. Accepted values are “down”, “up”, “towards_zero”, “towards_infinity”, “half_down”, “half_up”, “half_towards_zero”, “half_towards_infinity”, “half_to_even”, “half_to_odd”.

optionspyarrow.compute.RoundOptions, optional

Alternative way of passing options.

memory_poolpyarrow.MemoryPool, optional

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