How to find a min/max with Ruby

Question

I want to use `min(5,10)`, or `Math.max(4,7)`. Are there functions to this effect in Ruby?

Accepted Answer

`.min`

```
[5, 10].min
```

`.max`

```
[4, 7].max
```

They come from the Enumerable module, so anything that includes `Enumerable` will have those methods available.

v2.4 introduces own `Array#min` and `Array#max`, which are way faster than Enumerable's methods because they skip calling `#each`.

`.minmax`

@nicholasklick mentions another option, `Enumerable#minmax`, but this time returning an array of `[min, max]`.

```
[4, 5, 7, 10].minmax
#=> [4, 10]
```
