Description:¶ ↑

An utilities that is used by Mint.

Classes:¶ ↑

Mint::Expression¶ ↑

This class represents an expression.

expression = Mint::Expression.new('5 div 4', expression_tree)
p expression.to_s #=> '5 div 4'
p expression.to_maxima #=> '5 / 4'
p expression.to_latex #=> '5 \div 4'
p expression.normalize #=> '5 div 4'

Mint::Builder¶ ↑

This class builds expression from string.

input = Readline.readline('>')
begine
  answer = Mint::Builder.build(input)
  p answer.class
  #=> Mint::Expression
rescue
  puts 'Please check your answer.'
end
