C# 指数("E")格式说明符
csharpprogrammingserver side programming更新于 2025/9/15 18:22:00
("E")格式说明符将数字转换为以下形式的字符串 −
"-d.ddd…E+ddd"
或者
"-d.ddd…e+ddd"
上面，"d"是数字(0-9)。
在指数前加上"E"或"e"。
示例
using System;
using System.Globalization;
class Demo {
static void Main() {
double d = 3452.7678;
Console.WriteLine(d.ToString("E", CultureInfo.InvariantCulture));
Console.WriteLine(d.ToString("E10", CultureInfo.InvariantCulture));
Console.WriteLine(d.ToString("e", CultureInfo.InvariantCulture));
Console.WriteLine(d.ToString("e10", CultureInfo.InvariantCulture));
}
}
输出
3.452768E+003 3.4527678000E+003 3.452768e+003 3.4527678000e+003
