[Matplotlib-users] why does floor(x) return a float while docs state it returns integer?

[Mark B. <ma...@gm...>]

I expected that floor(x) would return an integer especially since the docs
state:

Return the floor of the input, element-wise.


The floor of the scalar `x` is the largest integer `i`, such that

`i <= x`. It is often denoted as :math:`\lfloor x \rfloor`.


Any reason why it returns a float? Bug/feature?


Thanks, Mark
