## Issue

I am seeing ^0 in the code base.

Example:

```
type stat struct {
...
min int64
...
}
newStat := stat{min: ^0}
```

What does ^0 mean?

## Solution

According to the docs:

^x bitwise complement is m ^ x with m = "all bits set to 1" for

unsigned x and m = -1 for signed x

So `^x`

inverts each of the bits in `x`

, eg. `0101`

becomes `1010`

. This means that `^0`

is the same as `~0`

in other mainstream languages.

When using two’s complement to represent negative numbers (which most programming languages do), the value of the bitwise complement of zero (where all bits are 1) is -1. So this is a way to write:

```
newStat := stat{min: -1}
```
