Scientific Calculator
Type a whole expression rather than pressing one button at a time. Supports the usual arithmetic plus trigonometric functions, logarithms, roots, powers and factorials, with standard operator precedence and parentheses for grouping.

About
What the Scientific Calculator does
Expressions are parsed by a purpose-built maths parser, not evaluated as code, so only the listed functions and constants can ever be reached. Trigonometric functions work in radians, which is the mathematical standard — for degrees, multiply by pi/180.
How it works
Using the Scientific Calculator
- 1Type your expression, for example sin(pi/6) + sqrt(16) * pow(2, 3).
- 2Use parentheses to group; multiplication and division bind tighter than addition and subtraction.
- 3Available functions include sin, cos, tan, ln, log, sqrt, cbrt, abs, exp, round, fact, pow, min and max.
- 4Constants pi, e and tau are recognised by name.
- 5The exact result and a rounded version are both shown.
Use cases
What people use it for
- Working through a physics or engineering formula
- Checking a multi-step calculation in one go
- Evaluating a logarithm or trigonometric value
- Computing a factorial or combination
