X 十六进制格式String.Format(“{0:X000}”,12) C 常用Convert类的类型转换方法 Convert。ToInt32() 转换为整型(int型) Conver.ToSingle() 转换为单精度浮点型(float型) Convert.ToDouble() 转换为双精度浮点型(double型) Convert.ToString() 转换为字符串类
同样,我们要先把字符串"31.0"转换成一个C#的小数类型(例如,float或decimal等),再转换为int类型就不会报错了: usingSystem;namespaceNetCoreConversion {classProgram {staticvoidMain(string[] args) {stringtext ="31.0";floatfloatNumber =Convert.ToSingle(text);intinteger1 =Convert.ToInt32(floatNumber);decim...
CAST(float_value AS SIGNED INTEGER) 1. SQL SERVER: ROUND(float_value , lenth) 1. lenth:小数点后面保留长度;结果四舍五入;
方法一：SELECT CAST('123' AS SIGNED integer);方法二：SELECT CONVERT('123',SIGNED);方法三：SELECT '123'+0;
