NumPy’s round function (often written asnp.round()ornumpy.round()) lets you round Python arrays of numbers to a specified decimal place. Here’s how to use it in its simplest form: import numpy as np # Simple array example arr = np.array([3.14159, 2.71828, 1.41421]) ...
原来Python2 的round()是四舍五入,而 Python3 的round()为四舍六入五成双,即高位为单数则进1凑成双数,高位为双数则不进位。 这让我想起了大二时候的大物实验,第一节讲的计数方法,其中印象最深刻的就是“四舍六入五成双”,它的作用是让统计数据更公平,降低舍入的误差。
Python round() Method The Python round() method rounds a number to a specific decimal place. This method returns a floating-point number rounded to your specifications. By default, the round() method rounds a number to zero decimal places. Let’s take a look at the syntax for the round(...
