# zero-integer-division

**Default severity:** `error`

Dividing two integer literals uses integer arithmetic. A fraction such as
`2 / 3` therefore truncates to zero, even when it is later converted or assigned
to a floating-point value.

Named constants are accepted to avoid warning on deliberate integer formulas.

## Bad

```go
ratio := 2 / 3
```

## Good

```go
ratio := 2.0 / 3.0
```
