Programmable Calculator

Programming Your Calculator

Create custom functions, set variables, and build reusable calculations. Perfect for engineering, science, and mathematical applications.

Creating Functions

• Name: Choose a descriptive function name
• Parameters: List input variables (comma-separated)
• Expression: Mathematical formula using parameters
• Execute: Run function with current variable values

Variables

• Set values for function parameters
• Add new variables by typing name and pressing Enter
• Update values dynamically for different calculations
• Remove variables using the × button

Expression Syntax

• Operators: +, -, *, /, ^ (power)
• Functions: sin, cos, tan, sqrt, abs, log, ln
• Constants: pi, e
• Variables: Any name you define
• Custom Functions: Use function_name(params)

Built-in Functions

• quadratic(a,b,c,x): Quadratic formula ax² + bx + c
• circleArea(r): Area of circle with radius r
• compound(p,r,t): Compound interest formula

Example: Custom Physics Function

1. Name: kinetic
2. Parameters: m, v
3. Expression: 0.5 * m * v^2
4. Set variables: m=2, v=10
5. Execute: kinetic(m,v) = 100 J
