# unicode_math ☻

You can have lots of fun with unicode in Ruby. Here are a few ways, and we'd love to see more!

## Usage

### Fractions

You can use many fractions as literals:

```
⅞ * 5
30 + ½
⅖ / ⅙
```

### Roots

You can use square root, cube root, and fourth root:

```
√ 4
∛ 27
∜ 81
```

### Trigonometry

There's a sine wave unicode character, so we can calculate sine of a number:

```
∿ π/2
```

### Constants

Easily use unicode costants:

```
π
τ
𝑒
∞
```

And have fun with them:

```
(-∞..∞).cover? ∞ + 1
```

### Exponents

You can raise to the powers of 0–9 as well as arbitrary numbers:

```
2.⁷
1.617 * 10.ⁿ(13)
```

### Division

```
21.÷ 7
6.⟌ 24
```

## Installation

Add this line to your application's Gemfile:

```
gem 'unicode_math'
```

And then execute:

```
$ bundle
```

Or install it yourself as:

```
$ gem install unicode_math
```
