Calculate the nth root of any number with precision guaranteed by server-side computation. Available via MCP in AI coding tools like Cursor and Windsurf, or REST API at `/v1/math/nth-root`. For example, the 3rd root of 27 returns exactly 3.0. Essential for mathematical calculations where floating-point precision matters.

}Use the nth-root tool directly in your AI assistant. Specify the number and the root index (n). The MCP tool handles the calculation server-side for precise results.
TinyFn's nth root uses server-side precision arithmetic, avoiding JavaScript's floating-point quirks. Math.pow(27, 1/3) might return 2.9999999999999996, while nth root returns exactly 3.0.
Yes, negative numbers work for odd roots (like cube root of -8 = -2). Fractional roots are supported. Even roots of negative numbers return complex number representations.
GET `/v1/math/nth-root` with query parameters for the number and root index. Returns JSON with the calculated result and metadata about the operation.
Server-side arbitrary precision arithmetic ensures mathematically correct results. No floating-point approximations or rounding errors that plague client-side calculations.
