Frequently Asked Questions – Digital Calculator
Numbers 0-9 for digits, +, -, *, / for operations, Enter or = for equals, Escape or C for clear, Backspace for delete, . for decimal point. F9 toggles sign, and Ctrl+M for memory operations.
MC (Memory Clear) sets memory to 0, MR (Memory Recall) displays stored value, MS (Memory Store) saves current display to memory, M+ adds current display to memory, M- subtracts current display from memory.
Trigonometric functions (sin, cos, tan), logarithms (log, ln), square root, powers (x², x^y), factorial, constants (π, e), reciprocal (1/x), absolute value, and exponential functions.
The calculator uses JavaScript’s native number precision (about 15-17 significant digits). Scientific functions use standard Math library implementations. For financial calculations requiring exact decimal precision, use dedicated financial calculators.
