如何始终在numpy中取整XX.5

import numpy as npA = [ [1.0, 1.5, 3.0], [2.5, 13.4, 4.1], [13.4, 41.3, 5.1]]A = np.array(A)print(A)def rounder(x):    if (x-int(x) >= 0.5):        return np.ceil(x)    else:        return np.floor(x)rounder_vec = np.vectorize(rounder)whole = rounder_vec(A)print(whole)

另外，您也可以查看numpy.ceil，numpy.floor，numpy.trunc以获得其他舍入样式
