How this service works
Evaluate an arithmetic expression with 64 significant digits (no floating point surprises): operators, parentheses, powers, roots, logs, trigonometry, percentages, constants, units (5 inch to cm) and simple statistics.
Output
Returns a JSON object containing the original expression string, the result type (e.g. 'number'), and the computed numeric result with up to 64 significant digits of precision.
Example use cases
Exact floating-point arithmetic
“What is 0.1 + 0.2 + 0.3 calculated with high precision, no floating point errors?”
Unit conversion in expression
“Convert 12.5 inches to centimeters for me using the expression '12.5 inch to cm'.”
Complex trigonometric formula
“Evaluate sin(45 degrees) * sqrt(2) + log(1000) for me with 64 digits of precision.”

Endpoint
GEThttps://qcb7fnxsbd7fbhj4.68r.lambda-web.us-east-1.on.aws/v1/math?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need exact numeric computation without floating-point rounding errors, especially for financial calculations, scientific formulas, unit conversions, or any expression where standard double-precision arithmetic is insufficient. Prefer it over general-purpose code execution for safe, sandboxed math evaluation with built-in support for units and scientific functions.
Side effects
- Expression exceeds 500 character limit — returns an error
- Invalid or unparseable expression syntax — returns parse error
- Unsupported function or operator — returns an error message
- Division by zero — returns an error
- Unsupported unit combination — returns an error
