Calculator app with Apple design but adding operation history

This is a simple calculator simulating Apple design but adding operations histroy

calculatorui's Issues

The application should look similar to the Apple Calculator app

Give the same addition priority to subtraction operation

The division operation is always returning zero as result

The multiply operations should be solved before addition operations

In order to solve a big problem like "sort the operations", as the first step, the app has to solve the multiply operations before addition operations

Percentage

Hi, beautiful control. What is your button sequence to calculate a percentage - specifically 50 + 10%?

Thanks

There is a mistake when user introduce 3 or more operands

Add sign change button functionality

Result expected

The number sign is changed:

• Positive -> Negative
• Negative -> Positive

Two or more operations can be done

Current situation:
The application can calculate only one operation due to the current implementation.

What is the problem:
The user would like to use the application more once when she has to solve several operations.

Solution:
When user tap on "AC" button

• Clean the view display
• Reset logic values

Minimal UI

There is a bug when the user try to chain operations

Add comma button functionality

Expected result

• The comma button adds a comma to the displayed number.
• The comma sign is integrated in order to calculate decimals numbers

Result as a new operation operand

Expected Result
To chain operations, the result will be the first operand in the next operation.

How we can do it?
To do this, the result would save as a first operand in the VM

Minimal Logic

Do an addition operation

The user must be able to tap the Equal button without causing a crash

The initial way to calculate operations + the result is shown on the display section

Add percentage button functionality

Result expected

Show percentage of the number inputted by the user

Clean and improve code [maintenance task]

Give the same multiplication priority to division operations

Clean smell code

• Calculate block has unnecessary code. CLEAN IT!

The result should not be print with decimals if decimals part does not exist
