A scientific calculator handles the maths that goes beyond basic arithmetic β from trigonometry and logarithms to powers and roots. All calculations run directly in your browser, so nothing is sent anywhere and the page loads instantly.
Unlike the basic calculator, this one respects standard operator precedence (PEMDAS/BODMAS) β multiplication and division happen before addition and subtraction, and powers (xΚΈ) are evaluated before both. Use the bracket buttons to group part of an expression and force it to be evaluated first, e.g. (2 + 3) Γ 4 gives 20, while 2 + 3 Γ 4 gives 14.
The DEG/RAD button in the top-left switches the angle unit used by sin, cos, and tan. DEG treats the number you enter as degrees (0β360Β°); RAD treats it as radians (0β2Ο). Most everyday and school-level trigonometry uses degrees; radians are the standard unit in higher mathematics, physics, and programming.
Function buttons (sin, cos, tan, ln, log, β, xΒ², 1/x) apply to whatever number is currently on the display. Ο and e insert their constant values directly. The memory buttons work like a physical calculator's memory: MS stores the current display value, M+ adds it to what's stored, MR recalls the stored value onto the display, and MC clears memory back to zero.
Very large or very small results are rounded to 12 significant figures to remove floating-point noise, which can occasionally show as a rounding difference in the final digit. ln and log are undefined for zero or negative numbers and will show "Error", matching real mathematical behaviour.
