如何在写入文件时舍入numpy堆栈数组?

我试图使用numpy.column_stack将多个数组写入一个文件,但无法将其舍入为两位小数。以下是可复制代码:

import numpy as np
A = np.array([1.1334, 4.10343, 12.4343])
B = np.array([2.1334, 5.12343, 16.23543])
C = np.array([4.1334, 4.3563, 18.36343])
np.savetxt('data.dat', np.around(np.column_stack((A, B, C)), decimals=2))

输出

1.129999999999999893e+00 2.129999999999999893e+00 4.129999999999999893e+00
4.099999999999999645e+00 5.120000000000000107e+00 4.360000000000000320e+00
1.242999999999999972e+01 1.623999999999999844e+01 1.835999999999999943e+01

简而言之,我希望将条目四舍五入到两位小数,并且可以使用此方法制表分隔条目吗。
