Software Development Cycle
THE PURPOSE OF THE PROGRAM
EasyCalculate is designed to simplify every single aspect of basic
calculation for our daily lives. The program is easy on the eyes,
easy on performance and resources, easy on everything. It
solves the problem of some calculators being overcrowded with
mathematical symbols, overcomplicating simple calculations
and such. Users can expect to have simplified experience while
using this very basic calculator that has 7 functions.
IT CAN:
-
Add
Subtract
Multiply
Divide
Calculate the root of a given number
Get exponents
Convert unit fractions into decimals
IT CAN’T:
- Do advanced calculations
- Assist in calculations that include over 2 values
- Assist in high-level problem solving
REQUIREMENTS SPECIFICATION
INPUTS
First value (diminished as Num1)
Second value (diminished as Num2)
OUTPUTS
Resultant value of any given operation within the calculator
Resultant value of string calculations
PROCESSING
The calculator will process the values given by the user with
extensive usage of VB operators, alongside with string codes
UI
The calculator’s interface will be as simple as it can get with
light colours and moderately spaced buttons without the usage
of any columns that indicate seperate areas of functions.
FINAL USER INTERFACE
