Root Calculator

Root Calculator – Quick Cheat Sheet

Definition: The n-th root of x is the number r such that rⁿ = x. Computed as x^(1/n).
Domain: For real results, even n requires x ≥ 0. Odd n allows negative x.
Precision: Set decimal places 0–12. Internally uses floating-point; extreme values may show rounding noise.
Verification: We re-raise the computed root to power n to show it’s ≈ x (within floating-point tolerance).
Batch: Drop a .txt/.csv with lines like 81,4 or 2 (defaults to square root). Processed entirely in your browser.
Tips: Square root → n=2; cube root → n=3; fourth root → n=4; etc.

Edge cases & notes

n = 0 is undefined and blocked.
Even root of a negative is not a real number; consider complex arithmetic for such cases.
Very large |x| or |n| may lead to underflow/overflow in floating-point arithmetic.
