# no-zero-fractions

[Added in v0.9.3](https://github.com/web-infra-dev/rslint/releases/tag/v0.9.3)
## Configuration

| Preset                              | Configured Value |
| ----------------------------------- | ---------------- |
| ✅ unicornPlugin.configs.recommended | `"error"`        |


```ts title=rslint.config.ts
import { defineConfig, unicornPlugin } from '@rslint/core';

export default defineConfig([
  unicornPlugin.configs.recommended,
  {
    rules: {
      'unicorn/no-zero-fractions': 'error',
    },
  },
]);
```

## Rule Details

Remove trailing zero fractions and dangling decimal points from numeric literals. For example, `1.0` becomes `1`, `1.010` becomes `1.01`, and `1.` becomes `1`. Numeric separators and exponent spelling are preserved outside the removed fraction.

The rule provides an automatic fix. It preserves required parentheses, keyword spacing, and statement boundaries when changing a numeric member receiver.

Examples of **incorrect** code:

```javascript
const value = 123_456.000_000;
const scale = 123.00e20;
const text = 1.00.toString();
```

Examples of **correct** code:

```javascript
const value = 123_456;
const scale = 123e20;
const text = (1).toString();
```

## Options

This rule has no options.
