Round to nearest Fields: AwayFromZero ToEven A round-to-nearest operation takes an original number with an implicit or specified precision; examines the next digit, which is at that precision plus one; and returns the nearest number with the same precision as the original number. For positive nu...
即Round to nearest with ties going to nearest even integer. 也就是只有在整数部分是奇数的时候, 小数部分才逢5进1; 偶数时逢5舍去。 这有利于更好地保证数据的精确性, 并在实验数据处理中广为使用。 >>> round(2.55, 1)#2是偶数,逢5舍去2.5 >>> format(2.55,'.1f')'2.5'>>> round(1.55, 1)...
输出ROUND_HALF_EVEN,即Round to nearest with ties going to nearest even integer方式进行进位。 我们我们要进行正确的四舍五入,我们将rounding指定为ROUND_HALF_UP即可。我们来看代码: fromdecimalimportDecimalfromdecimalimportROUND_HALF_UP,ROUND_HALF_EVENnum_1=Decimal('0.125').quantize(Decimal('0.00'),rou...
I would not suggest using the round() method to get the nearest integer, it is because the round() method uses banker's rounds, which can give an expected (for normal use) result. For example: round(2.5) # 2 round(2.5, 0) # 2.0 This post has info about that issue. To get the...
def myround(x, base=5): return base * round(float(x) / base) 这使我们可以使用非整数的基数,如.25或任何其他分数基数。 我意识到我迟到了,但似乎没有提到这个解决scheme: >>> from __future__ import division # This is only needed on Python 2 >>> def round_to_nearest(n, m): r = n...
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 a number to the nearest even number in Python Make sure to click on the correct subheading depending on how you need to round the number. # Round a float to the nearest 10th (0.1) in Python Use the round() function to round a float to the nearest 10th (0.1), e.g. result ...
Rounding datetime column to nearest quarter hourIf we use pd.Timestamp() method and pass a string inside it, it will convert this string into time format. We will use df.round() method and pass the amount of time as a string up to which we need to round up the time value....
Round to nearest, ties away from zero – rounds to the nearest value; if the number falls ...
