具有固定指数 C# 的科学记数法的双重价值

Question

我很有价值double value = 1427799000;

我想将其转换为科学计数法，其中指数值必须始终为 10^11 (E+11)。

我试过跟随，但没用。

Console.WriteLine(value.ToString("00.##E+11", CultureInfo.InvariantCulture));

输出应该是：0.14 x 10^11 or 0.14E+11

如何将双精度值转换为固定指数的科学计数法？这里的固定指数是 11.

Answer 1

double value = 1427799000;
Console.WriteLine(value.ToString("G2", CultureInfo.InvariantCulture));

//output: 1.4E+09

The General ("G") Format Specifier

The general ("G") format specifier converts a number to the most compact of either fixed-point or scientific notation, depending on the type of the number and whether a precision specifier is present.

编辑：关于您的评论，您不能以您想要的方式显示科学记数法，它不是那样定义的！系数必须大于或等于 1 且小于 10。

对于数字 1.23*10^11 ->Article source

The first number 1.23 is called the coefficient. It must be greater than or equal to 1 and less than 10.

The second number is called the base . It must always be 10 in scientific notation. The base number 10 is always written in exponent form. In the number 1.23 x 10^11 the number 11 is referred to as the exponent or power of ten.
