deffloat_to_two_decimal_places(number):number_str=str(number)result_str="{:.2f}".format(number)result=float(result_str)returnresult 1. 2. 3. 4. 5. 四、示例使用 我们可以通过以下代码来测试我们的函数: result=float_to_two_decimal_places(3.1415926)print(result) 1. 2. 这里我们调用了float_...
下面是一个完整的示例,将字符串转换为两位小数数字: defconvert_to_two_decimal_places(num_str):num_float=float(num_str)formatted_num="{:.2f}".format(num_float)returnfloat(formatted_num)num_str="3.14159"result=convert_to_two_decimal_places(num_str)print(result)# 输出:3.14 1. 2. 3. 4. 5...
print("Original Number: ", x) # Format the value of 'x' to two decimal places and include a sign (positive or negative) in the result. print("Formatted Number with sign: "+"{:+.2f}".format(x)) # Print the original value of 'y' with a label. print("Original Number: ", y) ...
圆形的工作原理如下:round(float_num, num_of_decimals) 所以在你的情况下你会这样做amount_per_day = round(amount_per_day, 2) 我还建议您将 print 语句中添加的所有令人讨厌的字符串替换为 f 字符串,如下所示: print(f"If you are going to spend {str(amount_of_money)} {str(destination_currency...
print("Area = ", round(area, 2)) Output: Area = 78.54 💡 Method 3: Using the Decimal Object Another workaround to our problem is to use the Decimal object, and the quantize function to return a float value with two decimal places. quantize method returns a value by rounding the fi...
We can use these functions to create custom methods to round up and down a given float value to two decimal places. Example Code: importmathdefr_down(number,decimals=2):a=10**decimalsreturnmath.floor(number*a)/aprint(r_down(7.852))defr_up(number,decimals=2):a=10**decimalsreturnmath...
>>> num = 4.123956>>> f"num rounded to 2 decimal places = {num:.2f}"'num rounded to 2 decimal places = 4.12'如果不做任何指定，那么浮点数用最大精度 >>> print(f'{num}')4.123956 格式化百分比数 >>> total = 87>>> true_pos = 34>>> perc = true_pos / total>>> perc0....
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(...
a, b, c, d = 20, 5.5, True, 4+3j print(a, b, c, d) # 20 5.5 True (4+3j) print(type(a), type(b), type(c), type(d)) # <class 'int'> <class 'float'> <class 'bool'> <class 'complex'> Python也可以这样赋值: ...
print(f'{val}') print(f'{val:.2%}') In the program, we display the 1/7 value as a percentage with two decimal places. $ python main.py 0.14285714285714285 14.29% Format width The width specifier sets the width of the value. The value may be filled with spaces or other characters if...
