pyspark.pandas.DataFrame.floordiv

DataFrame.floordiv(other)

Get Integer division of dataframe and other, element-wise (binary operator //).

Equivalent to dataframe // other. With the reverse version, rfloordiv.

Among flexible wrappers (add, sub, mul, div) to arithmetic operators: +, -, *, /, //.

Parameters

otherscalar

Any single data

Returns

DataFrame

Result of the arithmetic operation.

Examples

>>> df = ps.DataFrame({'angles': [0, 3, 4],
...                    'degrees': [360, 180, 360]},
