RandomAccessFile in = new RandomAccessFile("BOT.grd", "r");
in.seek(28);
double xll=in.readDouble();
以上是该代码,即用于阅读从29个到36个星号的双重数据。 现有价值为500,但正在达到2.08E-317。
看来这一档案存放在另一个不同的Endianness,而不是一个java用途。 或许需要扭转,然后才能翻一番,你可以尝试将以下法典改为价值:
long l = in.readLong();
double d = Double.longBitsToDouble(Long.reverseBytes(l));
这里是一个说明问题的例子:
double d = 500.0;
long l1 = Double.doubleToLongBits(d);
long l2 = Long.reverseBytes(l1);
System.out.println(Double.longBitsToDouble(l1));
System.out.println(Double.longBitsToDouble(l2));
