In this article, we will learn to round of floating value to two decimal places inPython. We will use some built-in functions and some custom codes as well. Let's first have a quick look over what are Python variables and then how to round off is performed in Python. Python Float Typ...
Round Float to Decimals Write a Python program to round a floating-point number to a specified number of decimal places. Sample Solution: Round to specified Decimals using %f Function: Python Code: # Define the order amount as a floating-point number.order_amt=212.374# Print the total order...
round()函数可以接受两个参数,第一个参数是要进行截断的浮点数,第二个参数是要保留的小数位数。为了截断浮点数后面的小数,可以将小数部分与整数部分相加后取整数部分。具体实现如下: 代码语言:txt 复制 import math def truncate_float(num, decimal_places): integer_part = int(num) # 获取整数部分 decimal...
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 places to round by providing a value in the second argument. The example...
help(round) # 应用一:金融计算 # 示例1:简单的四舍五入(使用Python内置的round()函数) def round_financial_simple(value, decimals=2): return round(value, decimals) # 示例 print(round_financial_simple(2.555, 2)) print(round_financial_simple(2.545, 2)) ...
With precision argument, it rounds to specified decimal places. The function returns a float even when rounding to whole numbers with precision specified. Bankers Rounding ExplainedPython uses "round half to even" (bankers rounding) which minimizes bias in statistical operations. This example ...

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。
Now, let’s round this value to two decimal places. We use the round() method. The round() method. lets you round a value to the nearest integer or the nearest decimal place. We also print the amount each friend has to contribute toward dinner to the console: rounded_value = round(...
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。 # 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. ...
