Function nthRoots #
Calculate the nth roots of a value. An nth root of a positive real number A, is a positive real solution of the equation “x^root = A”. This function returns an array of Complex values. Note that currently the precision of Complex numbers are limited to the precision of a 64-bit IEEE floating point, so even if the input is a BigNumber with greater precision, rounding to 64 bits will occur in computing the nth roots.
