4. 使用示例 (Usage Examples) 4.1 四舍五入为整数 (Rounding to the Nearest Integer) print(round(3.6)) # 输出: 4print(round(3.3)) # 输出: 3 在这个示例中,3.6被四舍五入为4,而3.3则被四舍五入为3。 4.2 指定小数位数 (Specifying the Number ofdecimalPlaces) print(round(3.14159, 2)) # 输...
Round values down to the nearest full integer roundA = math.floor(valueA) roundB = math.floor(valueB) roundC = math.floor(valueC) roundD = math.floor(valueD) roundE = math.floor(valueE) Print the results print(valueA, “rounded =”, roundA) print(valueB, “rounded =”, roundB)...
print(round_financial_down(2.555, 2)) # 输出: 2.55 print(round_financial_down(2.545, 2)) # 输出: 2.54 # 2.56 # 2.55 # 2.55 # 2.54 # 示例3:处理货币值(确保结果为整数,因为货币通常没有小数位) def round_to_nearest_cent(value): return int(round(value * 100)) # 示例 print(round_to_...

>>> import math >>> math.ceil(2.2)3 math.floor(x) 返回<= x 的最大整数 (int) Rounds x down to its nearest integer and returns that integer. >>> import math >>> math.floor(3.6)3 math.fabs(x) 返回x 的绝对值 Returns the absolute value for x as a float. >>> import math ...
Finally, to round to the nearest integer using the rounding half to even strategy, use np.rint(): Python >>> np.rint(data) array([[-1., -2., -1., 1.], [ 1., 1., -0., 0.], [-0., -1., 0., -1.]]) You might have noticed that a lot of the rounding strategies...
You can use round() to round a number to the nearest integer:Python >>> round(2.3) 2 >>> round(2.7) 3 round() has some unexpected behavior when the number ends in .5:Python >>> round(2.5) 2 >>> round(3.5) 4 2.5 is rounded down to 2, and 3.5 is rounded up to 4. ...
Today, we’re going to take a look at how to use ROUND(), common mistakes when using ROUND(), and alternatives to the ROUND() function. An introduction to the Python ROUND() function The ROUND() function takes a single number as an input and rounds it to the nearest integer. For ex...
