# impossible-integer-comparison

**Default severity:** `warning`

An integer type's minimum and maximum values make some comparisons always
true or false, such as checking whether an unsigned value is below zero or
above its maximum. Target-sized `int`, `uint`, and `uintptr` use the loaded
build architecture.

## Bad

```go
if value < 0 { use() } // value is unsigned
```

## Good

```go
if value == 0 { use() }
```
