Frequently Asked Questions
Can I type a full expression from my keyboard?
Not directly. This version is button-driven: you build the expression with the on-screen buttons and then press =.
Does sin(90) use degrees or radians here?
It depends on the active angle mode. The Deg/Rad toggle changes how sin, cos, and tan interpret their arguments.
Which functions and constants are actually supported?
The parser supports parentheses, +, -, *, /, exponentiation (^), postfix %, sin, cos, tan, log, ln, sqrt, and the constants pi and e. It does not include factorial, inverse trig, or scientific-notation shortcuts.
What does the % button do in this calculator?
It is a postfix operator that divides the preceding value by 100. For example, `50%` becomes 0.5 and can be used inside larger expressions.
Why do I get Error for some expressions?
The parser throws specific errors for division by zero, missing closing parentheses, negative square roots, non-positive log inputs, and unsupported function names instead of guessing what you meant.
