def convert_to_percentage(decimal_number): decimal_number = Decimal(decimal_number) percentage = decimal_number * 100 return f"{percentage:.2f}%" 示例 decimal_number = 0.1234 print(convert_to_percentage(decimal_number)) 3. 优点 高精度:使用decimal模块可以避免浮点数运算中的精度问题。 灵活性:可以...
下面是一个简单的类图示例,展示了一个名为PercentageConverter的类,它包含了一个方法convert_decimal_to_percentage来实现小数转化为百分数的功能。 PercentageConverter- decimal: float+convert_decimal_to_percentage(decimal: float) : str 在这个类图中,PercentageConverter类包含一个私有属性decimal和一个公有方法convert...

print(f"{num} rounded to 2 decimal places is {rounded_num}") round()是一种很好的舍入值的方法,但是如果您只是为了显示它们而舍入值,那么您可以考虑使用下一节中描述的技术。当你准备好了,你可以进入下一部分。Remove ads以样式打印数字向用户显示数字需要将数字插入字符串。您可以通过用花括号将分配给...

Euler’s number (e) is a constant that is the base of the natural logarithm, a mathematical function that is commonly used to calculate rates of growth or decay. As with pi and tau, Euler’s number is an irrational number with infinite decimal places. The value of e is often ...
Another key difference is thatnp.round()preserves thedata type, while Python’sround()converts to integers when decimals=0: # Python's round x = 3.7 y = round(x) print(y, type(y)) # Output: 4 <class 'int'> # NumPy's round ...
Percentage F-strings can also be used to display percentages. By using the percent format specifier (%), you can easily convert a decimal value to a percentage, and you can control the number of decimal places shown. main.py #!/usr/bin/python ...
