Написать уточняющие вопросы к требованиям. The list of the requirements for the calculator application. Business Requirements: Employees of our company need a calculator application. User Requirements: User can work in 2 modes – simple and scientific. In simple user can add, subtract, multiply and divide. In scientific user can perform squaring and square root extraction. The user is to be able to see the actions performed and the result. User should have an access to user guide. Functional Specifications: The following mathematical operations are supported with four types of numbers: positive, negative, integer and fractional numbers in “Simple” mode: Addition Subtraction Multiplication Division In “Scientific” mode supports all functions of “Simple” mode. In “Scientific” mode supports 2 additional operations with four types of numbers: positive, negative, integer and fractional numbers: Squaring Square root extraction There no installation, app is started by clicking on the .exe file; There should be an opportunity to create a sequence of calculations, e.g. 1+2+4*3, in this case all record is displayed in I/O field and result appears only after clicking on “=” button or pressing “Enter” button on keyboard. In such cases, like division by Zero or square root of negative number or any other incorrect operation, application has to drop the result to “0” without any additional notification or an error. Option “Mode” in menu bar consist of 2 option: “Simple” and “Scientific” Buttons of squaring and square root should be displayed after changing the mode to “Scientific” only; System and Non-Functional Specifications: Application should be downloaded to PС as .exe file Programming language is Delphi. OS support is Windows 7-10 latest builds. The language of the application is Russian. Application size should be less than 100 Mb. In the top left corner there is a small picture of calculator and the name of application – «Calculator ». Font size of all signatures has to be equal. Font color is black. Capacity of input/output field should be at least 20 symbols. Input/output field color is white. GUI Specifications: To open the application, you should double-click on the calculator executable file. The default value in the I/O field is 0. Keyboard layout (additionally see Picture 1): Numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 Arithmetical buttons for simple mode: + for addition – for subtraction * for multiplication / for division Additional arithmetical buttons for scientific mode: x2 for squaring √ for square root extraction Action buttons: = for result of the calculation C for removal of data in I/O field < for last character deletion (from right to left); To minimize the application, you should press button «_»; To close the application, you should press button «x»; Input field must contain 20 signs max. There are 2 options in menu bar – “Mode” to select calculator mode and “User guide” to get user guide
