💡 About precision

Decimal places determine how many digits after the decimal point are shown. More iterations allow methods to converge closer to the true value, especially for large numbers.

Step 2: Algorithm

10–10

📐 How it works

Newton & Babylonian use iteration xₙ₊₁ = 0.5·(xₙ + S/xₙ). Binary search halves an interval. Tolerance 10⁻ⁿ stops when change is below that value.
