LabVIEW Calculator

Note

This project was created as a learning exercise while I was studying LabVIEW.
As such, it may contain mistakes, non-standard implementations, or unnecessarily verbose logic due to my limited familiarity with LabVIEW’s built-in VIs.

Version

LabVIEW Community 2025 Q3

Features

• Basic arithmetic operations (addition, subtraction, multiplication, division)
• Square root calculation
• Parentheses (supports nested expressions)
• Sign toggle (+/–)
• Reciprocal function (1/x)
• Real-time clock display
• Execution duration timer
• Calculation history (stores recent results)

Implementation Details

• The calculator evaluates the entire expression only after pressing the "=" button, rather than performing step-by-step calculations.
• The expression parser is implemented using the Shunting Yard Algorithm, which efficiently handles operator precedence and parentheses without recursion.
