Sorting a Table

Hmmm

I'm confused.  Supposedly, if you interpret the 64 bits of a double FP as a 64-bit signed integer, it will sort correctly.

But I observe this:

What am I missing?

I haven't studies it in detail, but it might have to do with the fact that negative integers are in Two's complement.

[paul_a_cardinale]

In both Double, and I64, the MSB is 1 for negative, 0 for positive.

[altenbach]

I was talking about the remaining bits, which are in two-s complement for negative numbers.

For example in l8,

1 = b00000001

-1 = b11111111 (i.e. not b10000001)
