3-Way Scientific Calculator

A scientific calculator built through three different algorithms.

Prerequisites

1. Tools and Packages

   • python standard library (math, time, random, argparse)
   • numpy
   • pygame

2. Environments

   • python 3.8+ (windows.macOS.Linux均可，須有對應bash檔案）

Execution

1. Scientific Calculator User Interface python3 ./GUI.py

   • Click buttons on screen to add operands or numbers to your input.
   • Trigonometry functions are default to take radians as input
   • Precision was set to three digits behind the decimal point
   • See Amendable Variables for more details

2. Scientific Calculator Algorithms python3 ./parse_tree.py, python3 ./dp.py, python3 ./shunting_yard.py

   • Each uses algorithms of Parse Tree, Parse Tree + Recursion, and Shunting Yard respectively, see report 技術報告.pdf for more details

3. Test data generation python3 ./exp_generator.py

   • Generates test data of variety length and complexity: input.txt

4. Bash Testing

   • for Windows
     • correctness: bash evaluation_win.sh
     • time: bash time_evaluation_win.sh
   • for MacOs/Ubuntu
     • correctness: bash evaluation_macOs.sh
     • time: bash time_evaluation_macOs.sh

Amendable Variables

(python3 ./parse_tree.py, python3 ./dp.py, python3 ./shunting_yard.py)

• Input and output filenames: go to if__name__ == 'main' and change variable default

  parser.add_argument("--input", type=str,default='./correctness/correct_1.txt',help="Input file root")
  parser.add_argument("--output", type=str, default='./ouput_1.txt', help="Output file root")

• Amend angle units: go to class Calculator,__init__ and change self.angle； True for degrees, and False for radians

  class Calculator
  	def __init__(self):
  		self.angle = True
  		self.rnd_to = 3

• Amend output perciion: go to class Calculator,__init__ set self.rnd_to, the default value is 3

工程計算機

此專案以三種不同的演算法建置工程計算機: Parse Tree, Parse Tree + Recursion, Shunting Yard

安裝環境及使用套件

1. Tools and Packages

   • python standard library (math, time, random, argparse)
   • numpy
   • pygame

2. 執行環境

   • python 3.8以上 (windows.macOS.Linux均可，須有對應bash檔案）

程式檔案與執行

1. 計算機界面 python3 ./GUI.py

   • 進入GUI計算機頁面，操作與一般計算機相同，使用滑鼠點按即可
   • 程式預設: 三角函數輸入單位為度數、精準度為小數點後第三位，可調整python3. /shunt_yard.py 更改

2. 計算機演算法 python3 ./parse_tree.py, python3 ./dp.py, python3 ./shunting_yard.py

   • 分別對應 Parse Tree, Parse Tree + Recursion, Shunting Yard 演算法，詳情見技術報告說明

3. 測資生成 python3 ./exp_generator.py

   • 產生長度、複雜度相異的input.txt

4. bash 測試

   • for Windows
     • correctness: bash evaluation_win.sh
     • time: bash time_evaluation_win.sh
   • for MacOs/Ubuntu
     • correctness: bash evaluation_macOs.sh
     • time: bash time_evaluation_macOs.sh

計算機演算法參數調整

(python3 ./parse_tree.py, python3 ./dp.py, python3 ./shunting_yard.py)

• 調整輸入輸出檔案名稱: 至 if__name__ == 'main' 更改 default 參數

  parser.add_argument("--input", type=str,default='./correctness/correct_1.txt',help="Input file root")
  parser.add_argument("--output", type=str, default='./ouput_1.txt', help="Output file root")

• 調整輸入角度: 至 class Calculator,__init__ 調整 self.angle； True 為度數(預設)、False 為弧度 (限三角函數)

  class Calculator
  	def __init__(self):
  		self.angle = True
  		self.rnd_to = 3

• 調整輸出精準度: 至 class Calculator,__init__ 調整 self.rnd_to，預設值為 3
