Original array: [-0.7 -1.5 -1.7 0.3 1.5 1.8 2. ] Round elements of the array to the nearest integer: [-1. -2. -2. 0. 2. 2. 2.] Explanation:numpy.rint function is used to round elements of the array to the nearest integer. The values are rounded to the nearest integer....
numpy.round(arr, decimals=0, out=None) NumPy round() function parameters required Here, NameDescription arrThis is the input array in Python that we want to round, decimalsAn integer that determines the number of decimal places to which the values are rounded. The default value is 0. ...
Compares -0.9 to 0, here x < 0 so Put 0 in resulting array. Compares 0.5 to 0, here 0 <= x <1 so Put 1. Compares 5.4 to 4, here 3<=x so Put 4 18、reshape 它是NumPy中最常用的函数之一。它返回一个数组,其中包含具有新形状的相同数据。
NumPy Effective for rounding arrays using np.ceil() Requires the NumPy library Data analysis on large datasets. Handling Rounding Bias Rounding bias refers to the distortion of numerical values when using rounding methods. It usually occurs because rounding a number adjusts to an approximate value ...

Notes --- For values exactly halfway between rounded decimal values, Numpy rounds to the nearest even value. Thus 1.5 and 2.5 round to 2.0, -0.5 and 0.5 round to 0.0, etc. The rule "0.5 always rounds up" is commonly learned in schools, but it is not the only rule. Round-0.5-to-...
