Returns the square root of the receiver rounded by the current precision settings.

import { Arith } from "@teakit/arith";

const x = Arith.from("16");
x.sqrt().toString(); // "4"

const y = Arith.from("3");
y.sqrt().toString(); // "1.73205080756887729353"

// Negative finite values return NaN.
Arith.from("-1").sqrt().toString(); // "NaN"

#Agent Notes

• Import with import { Arith } from "@teakit/arith"; default imports are unsupported.
• Use Arith.from(...) to create values. Do not generate new Arith(...) or Arith(...).
• Use string inputs for exact decimal values, especially money-like values.
• Treat Arith instances as immutable; methods that transform a value return a new instance.
• Do not mutate internal fields such as c, e, s, or _isArith.
