可以看到，对于比较小的2的幂次方，浮点数是非常精确的。

As you can see, floats are pretty accurate for small powers of two.

每个距离的大小为2 的幂次方减一，因此这里有一个明确的模式。

The size of each gap is one less than a power of two, so there's a definite pattern here.

另外一种方法称为buddymemoryallocation，是一种更快的内存分配技术，它将内存划分为2的幂次方个分区，并使用best - fit方法来分配内存请求。

Another approach, called buddy memory allocation, is a faster memory technique that divides memory into power-of-2 partitions and attempts to allocate memory requests using a best-fit approach.
