Scientific Calculator
Trigonometry, logarithms, powers, roots and constants with expression parsing.
Type directly with your keyboard (numpad works too) and press Enter, or tap the buttons. Supported functions: sin cos tan ln log sqrt abs exp · constants: π e.
About this calculator
Full scientific functions — sin/cos/tan (radian measure), their precision via nested parentheses, natural and base-10 logarithms, exponentiation (^), square roots, absolute value and e^x — with π and Euler's e built in.
Type naturally (sqrt(16)+2^3, sin(pi/2)) or use the function keypad. Operator precedence follows standard mathematics: ^ binds tighter than × ÷, which bind tighter than + −.
Frequently Asked Questions
Why radians for trigonometry?
Radians are the mathematical standard and what every serious tool defaults to. For degrees, convert first: multiply by π/180.
Precision limits?
Results carry IEEE-754 double precision (~15–16 significant digits); display rounds to 12 significant figures to hide floating-point noise.
