float 是单精度浮点型 ,double 是双精度浮点型 ,long double是长双精度类型,所占字节长度不一样,有效数字长度不一样(也就是精度不一样),指数范围也不一样。long double在有的编译器和double长度是一样的,这种情况下那就跟double没区别了 78.9 这种一般默认按double类型处理 如果加F或者f 如 42f 、54.2F则按...

The library makes the false assumption that time_t is equivalent to long. To avoid the year 2038 problem Linux distributions like Debian and Ubuntu have moved to using 64-bit time_t on 32-bit architectures like ARMv7. Now we see test failures like: FAIL tltest-timespec.c:169 -2147483648.9...
while(reader.Read()) {byte[] buffer =newbyte[4000];longbyteCount = reader.GetBytes(1,0, buffer,0,4000); } 使用GetValue 检索数据 SqlDataReader的GetValue方法将值从指定的列偏移量读入数组。 下面的代码段假定一个名为reader的SqlDataReader对象,该对象从第一个列偏移量检索二进制数据,然后从第二列...
The following example uses theMinValueandMaxValuefields to verify that anInt64value is within the range of theUInt32type before it performs a type conversion. This verification prevents anOverflowExceptionat run time. C# longlongValue =long.MaxValue /2; uint integerValue;if(longValue <= uint....
Represents the largest possible value of anInt64. This field is constant. C# publicconstlongMaxValue =9223372036854775807; Field Value Value = 9223372036854775807 Int64 Remarks The value of this constant is 9,223,372,036,854,775,807; that is, hexadecimal 0x7FFFFFFFFFFFFFFF. ...
