( Round to nearest with ties going to nearest even integer. ) 银行家舍入法的具体计算规则: •(1)被修约的数字小于5时,该数字舍去; •(2)被修约的数字大于5时,则进位; •(3)被修约的数字等于5时,要看5前面的数字,若是奇数则进位,若是偶数则将5舍掉,即修约后末尾数字都成为偶数;若5的后面还...
This example shows round with different numbers. Without precision, it rounds to nearest integer. Note the bankers rounding for 0.5 cases. With precision argument, it rounds to specified decimal places. The function returns a float even when rounding to whole numbers with precision specified. ...
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...
integer_number = int(rounded_number) # Or simply: int(round(float_number)) print(integer_number) Output: 8 You can refer to the below screenshot to see the output. Theround()function rounds to the nearest integer. If the decimal part is exactly 0.5, Python rounds to thenearest even num...

1、浮点数的精度问题:由于计算机内部表示浮点数的方式,有时候round()函数的结果可能不是完全符合预期,这通常发生在需要高精度的金融计算或科学计算中。例如,round(2.675, 2)在某些情况下可能返回`2.67`而不是`2.68`。 2、四舍五入规则:round()函数使用标准的四舍五入规则,即如果小数点后的第三位是5或更大,则...
