How to properly round numpy float arrays

I have some sort of rounding issue when rounding floats.

x = np.array([[1.234793487329877,2.37432987432],[1.348732847,8437.328737874]])

array([[ 1.23000000e+00, 2.37000000e+00],
[ 1.35000000e+00, 8.43733000e+03]])

Is there a way to display these numbers without the zero extensions?

Rounding floating point numbers is almost never needed (unless you want to bucket them, then your code will work just fine), if you only want to print them with less precision, use this:

print(np.array_str(x, precision=2))
