Exercise: How to round away from zero a float array?
Problem:
Z = np.array([1.4])
np.trunc(Z + np.copysign(0.5, Z)) # prints 1. instead of 2.
Z = np.array([1.0])
np.round(Z + np.copysign(0.5, Z)) # prints 2. instead of 1.
Solution:
Z = np.array([1.0, 1.4])
np.copysign(np.ceil(np.abs(Z)), Z) # prints correct [1., 2.]
