# unicorn/no-zero-fractions

> Disallow numbers with a zero fraction or a dangling dot

`1.0`, `1.` and `1` are the same number. JavaScript has no separate integer and float types, so the extra zeros and the dot suggest a difference that isn't there.

`--fix` removes the zeros and the dot.

## Configure

Off by default. To turn it on:

```toml bunfig.toml
