[removed] Calculate the nth root of a number

Question

I\'m trying to get the nth root of a number using JavaScript, but I don\'t see a way to do it using the built in Math object. Am I overlooking something?

Answer 1

Use Math.pow()

Note that it does not handle negative nicely - here is a discussion and some code that does

function nthroot(x, n) {
  try {
    var negate = n % 2 == 1 && x < 0;
    if(negate)
      x = -x;
    var possible = Math.pow(x, 1 / n);
    n = Math.pow(possible, n);
    if(Math.abs(x - n) < 1 && (x > 0 == n > 0))
      return negate ? -possible : possible;
  } catch(e){}
}
