Let arr be a $1-$dimensional NumPy array. Assuming that all the elements in arr are nonnegative floating$-$point

numbers. Write a function that rounds all the numbers in arr to the nearest integers.

Hint: Operators $//$ and $\%$ might be helpful.

For example, if arr is $[1\mathrm{.}4,0\mathrm{.}3,3\mathrm{.}8,89\mathrm{.}0,0,0\mathrm{.}5,44],$ you should return $[1,0,4,89,0,1,44]$ instead of $[1.0.4.$

$89.0.1.44.]$
