Scientific Calculator API

POST https://api.findutils.com/api/tools/scientific-calculator/execute

Evaluate a scientific math expression and return the numeric result (12 significant digits). Supports + - * / ^ (or **), parentheses, n!, π (or pi), e, and the functions sin, cos, tan, asin, acos, atan, sinh, cosh, tanh, asinh, acosh, atanh, log (base 10), ln, sqrt (or √), cbrt, abs, exp. An nth root is x^(1/n). Trigonometry in radians or degrees; hyperbolic functions take a plain number and ignore the angle unit. Uses a safe parser — no code execution.

expression

string required

Expression to evaluate, e.g. "sin(30) + 2^3 * (4 - 1)" or "5! / sqrt(16)".
angle_unit

string optional

Angle unit for sin/cos/tan inputs and asin/acos/atan outputs. One of rad · deg. Default "rad".
