Frequently Asked Questions
What functions does this scientific calculator support? +
This calculator supports basic arithmetic (+, −, ×, ÷), trigonometric functions (sin, cos, tan, and their inverses), logarithms (log base 10 and natural log), exponents, square roots, factorials, constants (π and e), parentheses, and memory operations (M+, M−, MR, MC).
Are the trigonometric functions in degrees or radians? +
You can toggle between degrees and radians using the DEG/RAD button. The current mode is displayed on the button itself. By default, the calculator uses degrees.
How do memory functions work? +
M+ adds the current result to memory, M− subtracts it from memory, MR recalls the stored memory value to the display, and MC clears the memory. A small "M" indicator appears when a value is stored in memory.
Can I use keyboard input with this calculator? +
Yes! You can type numbers, operators (+, -, *, /), parentheses, and press Enter to calculate. Press Escape to clear the display, and Backspace to delete the last character.
Is this calculator accurate for complex calculations? +
Yes, this calculator uses JavaScript's built-in Math library for high-precision floating-point arithmetic. It handles order of operations correctly and supports nested parentheses for complex expressions.
