| name | calculate |
| description | Compute the value of a math expression. Handles arithmetic, algebra, trig, calculus. Use this instead of LLM arithmetic — calculate is exact and deterministic. |
| args | {"expression":"required string — the math expression, e.g. \"2 + 3 * sqrt(7)\" or \"x**2 - 4 = 0\"","vars":"optional string — variable bindings as \"name=value, name=value\", e.g. \"v=20, theta=30, g=9.8\"","precision":"optional int (default 10) — decimal places for the result"} |
calculate
Numerically evaluate mathematical expressions via SymPy. Returns the result as a string.
Supported operations
- Operators:
+, -, *, /, **, %
- Constants:
pi, E
- Functions:
sin, cos, tan, asin, acos, atan (radians), sqrt, log, ln, exp, abs, factorial
- Equations: an expression containing
= is solved (e.g. x**2 - 4 = 0 → -2.0, 2.0)
All trig functions expect radians.
