Scientific Calculator
Evaluate expressions with trigonometry, logarithms, powers, roots, factorials, and common constants.
Scientific calculator
Type an expression or use the buttons. Use * for multiplication. Functions require parentheses.

How to use the scientific calculator
- Enter an expression in the field or build it with the calculator buttons.
- Select degrees or radians for trigonometric functions.
- Use parentheses to group operations, and use
*for multiplication. - Select Calculate or press Enter. Use
Ansto insert the previous result.
Example: In degree mode, enter sin(30) + log(100). The result is 2.5, because sin(30°) is 0.5 and log₁₀(100) is 2.
Supported operations
Addition, subtraction, multiplication, division, unary signs, powers, parentheses, factorials, π, e, square root, absolute value, exponential function (exp), base-10 logarithm (log), natural logarithm (ln), and trigonometric functions (sin, cos, tan, asin, acos, atan). Inverse trigonometric results use the selected angle unit.
Factorials accept whole numbers from 0 to 170. Logarithms require positive inputs; square roots require non-negative inputs. Division by zero, invalid expressions, and results outside the finite number range are reported instead of shown as valid answers. Results use JavaScript floating-point arithmetic, so the last few digits may be rounded.
