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 retu
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...
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)...
