As a math idiot
I want to be told the sum of two numbers
So that I don't make silly mistakes

Scenario: 50+70

• Given I have entered 50 into the calculator
• Given foo bar
• And I have entered 70 into the calculator
• When I add
• Then the result should be 12 on the screen
• And the result class should be Float

As a math genius
I want to be told the division of two floats
So that I don't make silly mistakes

Scenario: 7/2

• Given I have entered 3 into the calculator
• And I have entered 2 into the calculator
• When I divide
• Then the result should be 2.5 on the screen
• And the result class should be Float

Scenario: 3/0

• Given I have entered 3 into the calculator
• And I have entered 2 into the calculator
• When I divide
• Then the result should be NaN on the screen
