Python round FunctionLast modified April 11, 2025 This comprehensive guide explores Python's round function, which returns a floating point number rounded to specified digits. We'll cover basic usage, precision control, and practical examples of number rounding. ...
Let's dive deeper into rounding down in Python! What is round down? So far, we've discussed "Round off," which is the most general type of approximation. "Round down," while similar, is not the same. As the name implies, Round Down reduce a number to the nearest lower integer. ...
Q4. In Python, the round() function rounds up or down? The round() function can round the values up and down both depending on the situation. For <0.5, it rounds down, and for >0.5, it rounds up. For =0.5, the round() function rounds the number off to the nearest even number....
The ROUND() function is, obviously, most commonly used when you need to round a number to the nearest integer. For example, if you want to calculate the average of a set of numbers, you might need to round the final value up or down so that it’s an integer. While a computer won...

Python Decimal 模块中的 ROUND_HALF_EVEN 和 ROUND_HALF_DOWN 在Python 中,Decimal 模块提供了高精度的十进制浮点数运算,可以避免浮点数计算时出现的精度丢失问题。Decimal 模块中有两种常用的舍入模式:ROUND_HALF_EVEN 和 ROUND_HALF_DOWN。这两种舍入模式对于处理浮点数的舍入操作非常有用。
