Get numpy ceil and floor value for nearest two decimals

[paul18fr]

As I suggested:

import numpy as np
a = np.array([-1.784, -1.5888, -0.24444, 0.25555, 1.5, 1.75, 2.0])
a_rounded = np.around(a, decimals=2)
print(f"{a_rounded}")

Output:
[-1.78 -1.59 -0.24  0.26  1.5   1.75  2.  ]

Actually I'm just wondering if that's your need or if you're asking as well for "zeros" to complete decimals; for instance "1.5" and "2." must provide "1.50" and "2.00" respectively
