About this tool
Type an expression with powers, roots, logarithms, trigonometry and constants, and get an exact-as-possible result.
The expression is read by a strict parser that only knows numbers, + − × ÷ ^ %, parentheses, pi, e and whitelisted functions such as sqrt, root, ln, log, sin, cos, tan, asin, fact, ncr. Nothing else is ever executed.
Formula: sin(30) + 2^3 × √16
Example: Expression = (2 + 3) × sqrt(16) − 10 ÷ 4, Angle unit = Degrees → Result = 17.5.
log(x) is base 10 and ln(x) is natural. Choose degrees or radians for trigonometry. Results have about 15 significant digits.
Quick steps
- Enter your values — every field shows its unit.
- Press Calculate (or Try an example to see how it works).
- Read the results and copy them if you need them elsewhere.
The calculation runs in your browser. Nothing you type is sent to 1CLIK.
