MathSymbols
Support for mathematical syntactic sugars!
Installation
gem install math_symbols
Usage
This is how we should write function that calculates a fourier for a step function without this gem:
def traditional_way(x, n_max = 10)
(4/Math::PI) * (1..n_max).step(2).inject(0) do |acc, n|
acc += Math.sin(n*Math::PI*x)/n
end
end
traditional_way(0.5) # => 1.0630539690963425
This is how we can do with it:
require 'math_symbols'
using MathSymbols
sweet_way =
or
require 'math_symbols'
using MathSymbols
def sweet_way(x, n_max = 10)
Which one is easier to read and therefor maintain?
Usage Without Refinements
If you prefer not to use refinements, just load its core extensions in the same way that you would have done on ActiveSupport.
require 'math_symbols/core_ext'
Development
Run rake
to rubocop, RBS and RSpec tests.
