decimal是python中的标准库,直接将Decimal导入到代码块中使用。 decimal意思为十进制,这个模块提供了十进制浮点运算支持。通过几个常见的实战用例来说明一下其用法。 浮点数转Decimal 使用Decimal.from_float函数将随便一个float类型的小数转换成Decimal的数据类型,结果float类型数据就显出原形了。
使用Decimal.from_float函数将随便一个float类型的小数转换成Decimal的数据类型,结果float类型数据就显出原形了。 # It imports the Decimal class from the decimal module. import decimal from decimal import Decimal # It converts the float 10.245 to a Decimal object. ...
In this example, we've rounded my_float to two decimal places. Note: The round() function uses "round half to even" rounding, also known as "bankers' rounding". This means that if the number to be rounded is exactly halfway between two possible values, it will be rounded to the near...
Python provides different methods for rounding numbers to two decimal places. The following examples provide detailed explanations of these techniques. Round to 2 decimal places using the round() function The round() function is Python’s built-in function for rounding float point numbers to the sp...
