Function sqrtBig

Calculates the nth root of a Big instance with custom precision and rounding mode.

Note: it's the most weighted function in the library. It's reusing a lot of other functions, and it's not perfect in performance, recommended to use it only when you need it and with default precision and rounding mode. It uses the Newton's method to calculate the root.

Throws

• If the root is not an integer.

Example

const big1 = new Big(16);
console.log(sqrtBig(big1).toString()); // 4.00000000000000000000
console.log(sqrtBig(big1, 4, 0).toString()); // 2
console.log(sqrtBig(big1, 4, 1).toString()); // 2.0
console.log(sqrtBig(Big(0), 4).toString()); // 0
console.log(sqrtBig(Big(1), 4).toString()); // 1
console.log(sqrtBig(Big(-1), 4).toString()); // throws Error
console.log(sqrtBig(Big(16), 0.5).toString()); // throws Error
console.log(sqrtBig(Big(16), -2).toString()); // throws Error
console.log(sqrtBig(Big(16), 4, -1).toString()); // throws Error
