需要注意的是,int()函数只会将浮点数的整数部分保留,舍弃小数部分。如果希望对浮点数进行四舍五入,可以使用round()函数。 number=3.14integer=round(number)print(integer) 1. 2. 3. 输出结果为: 3 1. 在这个例子中,我们使用round()函数对浮点数进行四舍五入,并将结果赋值给变量integer。最后,我们打印出变量...
Round away from zero if last digit after rounding towards zero would have been 0 or 5; otherwise round towards zero. 如果rounding之后,最后的数字是0或5,就向UP方向(远离0的方向)舍入;否则,就像靠近0的方向舍入。 >>> Decimal('1.204').quantize(Decimal('.00'), rounding=ROUND_05UP) Decimal('...
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...
Note:When we convert float to int Python,the int() functiontruncates the decimal part of the number rather than rounding it to the nearest whole number. If we need rounding, we should usethe round() functionbefore converting to an integer. How to convert negative float value to int in Py...
整数由1-n个数字字符表示,整数的类型名称是int,所有的整数都是类型int的实例;浮点数由整数部分和小数部分构成,中间用.连接,浮点数的类型名称是float,所有浮点数都是类型float的实例;复数由实部和虚部构成,其中虚部跟上字母j,复数的类型名称数complex,所有复数都是类型complex的实例。
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...
math allows you to perform rounding with floor and ceil, provide the value of pi, and numerous other operations. Let's see how to use this library for rounding up or down.Rounding numbers enables you to remove the decimal portion of a float. You can choose to always round up to the ...
A: Python'sint()function does not support the conversion of a complex number to an integer. Attempting to do so will raise a TypeError. Q: What is the difference betweenfloor()andint()when converting a float to an int? A: Thefloor()function will always round down to the nearest integer...

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...
