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...
3. 使用decimal模块 Python的decimal模块提供了一种更加精确的方法来处理浮点数。通过Decimal类的quantize()方法可以对小数点位数进行精确控制。下面是一个示例: fromdecimalimportDecimal,ROUND_HALF_UP num=Decimal('3.14159')rounded_num=num.quantize(Decimal('0.01'),rounding=ROUND_HALF_UP)print(rounded_num) 1....
quantize方法的第一个参数是要保留的小数位数,通过传入Decimal('0.00')可以保留两位小数。第二个参数rounding指定了舍入方式,ROUND_HALF_UP表示四舍五入。 需要注意的是,decimal.Decimal类型的运算和普通的浮点数运算有所不同,需要使用其中定义的方法和函数。 总结 本文介绍了几种常用的方法来控制Python中浮点数的小数...
float_num=10.6int_num=int(float_num)print(int_num)# Output: 10 In this example, the float 10.6 is truncated to 10. Truncation vs. Rounding When converting a float to an int in Python, it's important to note that Python does not round the number to the nearest integer; instead, it ...
