Verification: Local fixtures; no external services
Updated: 2026-10-28

## Implementation

```javascript
function hoursAndMinutes(value) { return [Math.floor(value), Math.floor((value * 60) % 60)]; }
```

## Input

```json
1.5
```

## Expected output

```json
[
  1,
  30
]
```

## Edge case

Input:
```json
2.999
```
Output:
```json
[
  2,
  59
]
```

## Limits

- Minutes are floored, not rounded, as the edge case shows. The lab accepts 0 or more hours.

The lab validates types and size before calling this function. Add equivalent validation at your own trust boundary.
