So we started having some fun with Ruby yesterday:

# Get the square root of 5
√ 5  #  => 2.23606797749979 

# or see if infinity + 1 is still in the infinite range
(-∞..∞).cover? ∞ + 1  # => true

# or get the sine of pi / 2
∿ π/2  # => 1.0

# or do math with fractions
⅞ * ⅔ # => 0.5833333333333333

Now you can do all of this and more with the unicode_math gem!

Simply install the gem and you’re off and running.

gem install unicode_math

Check out the source code on GitHub. We’d love to see your ideas for more fun, so get those pull requests coming!

Finally, why would we do this‽ Because it was fun, and Ruby has great support for unicode. Enjoy!
