How this service works
Exact calculator: arithmetic, fractions, big integers, functions: Evaluates a math expression exactly: + - * / % ^ !, parentheses, big integers and fractions (1/3 stays 1/3), plus sqrt, round, floor, min, max, mean, gcd, lcm, comb, perm, ln, log, exp and trig (radians; deg constant). Returns result,
Output
A JSON object containing: result (canonical string), exact (boolean indicating if result is exact), fraction (fractional form if rational), decimal (decimal expansion to requested precision), scientific (scientific notation), integer (boolean), rounded (boolean), repeating (repeating decimal pattern if any), digits, decimals, expression (echoed input), tool name, and any notes about the computation.
Example use cases
Exact fraction arithmetic for finance
“What is (7/12 + 5/9) * 4 expressed as an exact fraction? I need the precise answer, not a rounded decimal.”
Factorial of a large integer
“Calculate 50! exactly for me — I need the full integer, no scientific notation shortcuts.”
Trigonometry with degree constant
“What is sin(45 * deg) computed exactly? Show me the result to 20 decimal places.”

Endpoint
GEThttps://shop.lordevo.com/api/quick/math-eval?utm_source=zero.xyzWhen to prefer
Choose this endpoint when exact symbolic or arbitrary-precision results are required — especially for fractions, big integers, or expressions involving pi, e, or standard math functions — rather than floating-point approximations. It is ideal for agents that need verifiable, lossless computation results rather than estimates from a general-purpose LLM.
Side effects
- Malformed expression returns error — e.g. mismatched parentheses or unknown function name
- Expression exceeding 1,000 characters is rejected
- Invalid decimals parameter (non-numeric or out of 0–100 range) returns validation error
- Division by zero returns error or undefined result
- Very deeply nested or computationally explosive expressions may time out
