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:

β…ž * 5
30 + Β½
β…– / β…™

Roots

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

√ 4
βˆ› 27
∜ 81

Trigonometry

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

∿ Ο€/2

Constants

Easily use unicode costants:

Ο€
Ο„
𝑒
∞
𝐒

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.Γ· 7
6.⟌ 24

Multiplication

5.Γ— 5

Sigma and pi notations

You can sum up or multiply emlements of either an array or range:

Ξ£ [1, 2, 3, 4]
Ξ£ (1..10)
Ξ  [1, 2, 3, 4]
Ξ  (1..10)

Array as set

[2, 3, 5, 7].∩ [3, 5, 7, 9]
[2, 3, 5, 7].βˆͺ [3, 5, 7, 9]
