This is my first laboratory work for OOP from KNU

Mini spreadsheet

Windows Forms Application C#

This is pretty spreadsheet created in Windows Forms that can help you make basic operations with cells and values.

Used:

• ANTLR4 for parsing expressions
• Windows Forms for GUI

Developing

git clone https://github.com/pashokred/mini_spreadsheet.git

And open it in IDE with .NET Core 3.1 and Windows Forms support

Features

There is all the bells and whistles this project can perform:

• The main functionality is to easy calculate expressions with double values and cell initializers

  In this form you can use next operations:

  * Arithmetic operations
  
    +, -, *, / (binar operations)
    ^ (put number in the power)
    
    mod (modulo operation or operation %) - returns the remainder or signed remainder of a division, after one number is divided by another)
    
    div (integer division) - is division in which the fractional part (remainder) is discarded is called integer division and is sometimes denoted
  
  * Logical operations:
  
    =, <, >
    <=, >=, <>
    (returns '1' if true and '0' if false)
  

• You can also do operations with cell identifiers:

• Create table by your own size, Add/Delete last rows and columns

• If you get really randy, you can even export this table in .xlsx format or import in table from files with extentions .xls, .xlsx, Excel WorkBook, Excel Workbook 97-2003.

Configuration

Argument 1

Returns result of Logical operation

Type: Double|String
Return: Double
Default: 0

A2 = 45; H4 = 7; F3 = 26; G3 = F3; B1 = 45; E5 = 16;

Example:

((A2+50) - H4*10) mod F3 + G3 div B1 > (E5/3)^4  # Prints 0

Argument 2

Returns result of Arithmetical operation

Type: Double|String
Return: Double
Default: 0

A2 = 45; F3 = 26; B1 = 45; E5 = 16;

Example:

(A2+45) / F3 mod E5 - 50 mod B1  # Prints -1.5384...
