You can also specify text alignment using the greater than operator:>. For example, the expression{:>3.2f}would align the text three spaces to the right, as well as specify a float number with two decimal places. Conclusion In this article, I included an extensive guide of string data typ...
decimal.getcontext() 返回活动线程的当前上下文。 decimal.setcontext(c) 将活动线程的当前上下文设置为c。 从Python 2.5开始,您还可以使用with语句和localcontext()函数临时更改活动上下文。 decimal.localcontext([c]) 返回一个上下文管理器,它将活动线程的当前上下文设置为进入with-statement时的c副本,并在退出with...

Round the number n to p decimal places by first shifting the decimal point in n by p places. To do that, multiply n by 10ᵖ (10 raised to the p power) to get a new number, m. Then look at the digit d in the first decimal place of m. If d is less than 5, round m ...
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 specified number of decimal places. You can specify the number of decimal ...
