问题描述
我有以下问题,所以我尝试了双转换成其二进制重新presentation,但使用这种 Long.toBinaryString(Double.doubleToRawLongBits(D))
没有帮助,因为我有大的数字,那么久不能存储他们即 2 ^ 900
。
I have the following problem, so I tried to convert a double to its binary representation, but using this Long.toBinaryString(Double.doubleToRawLongBits(d))
doesn't help, since I have large numbers, that Long can't store them i.e 2^900
.
鸭preciate任何帮助:)
Appreciate any help :).
推荐答案
Long.toBinaryString(Double.doubleToRawLongBits(D))
似乎工作就好了。
System.out.println("0: 0b" + Long.toBinaryString(Double.doubleToRawLongBits(0D)));
System.out.println("1: 0b" + Long.toBinaryString(Double.doubleToRawLongBits(1D)));
System.out.println("2: 0b" + Long.toBinaryString(Double.doubleToRawLongBits(2D)));
System.out.println("2^900: 0b" + Long.toBinaryString(Double.doubleToRawLongBits(Math.pow(2, 900))));
System.out.println("Double.MAX_VALUE: 0b" + Long.toBinaryString(Double.doubleToRawLongBits(Double.MAX_VALUE)));
/*
prints:
0: 0b0
1: 0b11111111110000000000000000000000000000000000000000000000000000
