在C++中没有现成的等效函数，但是您可以创建一个以类似方式工作的函数：
ToString("c"));//默认保留两位的货币表示 Console.WriteLine(number1.ToString("c5")); Console.WriteLine(number1.ToString("c1"));//保留小数点后几位的货币表示 int number2 = 123; Console.WriteLine(number2.ToString("d")); Console.WriteLine(number2.ToString("d5")); Console.WriteLine(number2....
//【C或c】,数字转换为表示货币金额的字符串。转换由当前 NumberFormatInfo 对象的货币格式信息控制。 //精度说明符指示所需的小数位数。如果省略精度说明符,则使用当前 NumberFormatInfo 对象给定的默认货币精度。 Console.WriteLine("(2.5).ToString('C'):" + (2.5).ToString("C", Culinfo)); //￥2.5 Conso...
