The stack calculator can take math expressions at the input, and push the result of the expression to a global stack. It is then possible to trigger functions on the stack.
Expressions supported:
- Infix expressions with parenthesis and function calls.
- Function names, with no parenthesis. These will take their arguments from the stack.
| Function | Result |
|---|---|
| 77 | will push 77 to the stack |
| 1+1 | will push 2 to the stack |
| 5*(3-abs(-5^2)) | will push -110 to the stack |
| + | will pop two numbers, perform their addition and push the result |
| sin | will pop 1 numbers, perform sinus and push the result |
