Calculate

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, 2). An explicit solve(...) call works too: solve(x**2 - 4, x).

All trig functions expect radians.

Exact vs floating-point results

An expression that evaluates to an exact integer or rational comes back exact — 17! returns 355687428096000, not 3.556874281e+14. precision applies only to results that genuinely need floating-point evaluation (irrationals, trig, logs). Asking for a small precision to get a "clean" integer is backwards and will be rejected below 1.
