- Create new instances of a
Calculatorclass with an initialized value - Access calculator methods from this class within
prywhen runningruby bin/calc.rb - Return
FloatsvsFixnumsfor true values
In bin/calc.rb, create a Calculator Class with an initialize
method that takes a starting number. You should then create calculation methods
for each of the following operations that take a second number to perform a
calculation on:
- Addition
- Subtraction
- Multiplication
- Division
After running ruby bin/calc.rb, and in your pry console, you should be able
to create a new instance of your Calculator class and chain a calculation
method to it to receive the correct answer.
Be aware of whether your methods are returning Float or Fixnum results.
Research Ruby's self,
specifically in regards to method chaining,
and refactor your Calculator class to allow for multiple chained
calculations. For example:
Calculator.new(5).add(3).multiply(2).subtract(1).divide(3) #=> 5
