/**
 * Constructs a polynomial from the given roots by multiplying out the
 * factors (x - root1)(x - root2) in double precision
 *
 * * the resulting polynomial may have complex roots close to zero due to
 * round-off caused by working in double precision.
 *
 * * mostly for testing purposes.
 *
 * * the real roots of the constructed polynomial is unlikely to be exactly
 * the same as the roots that the polynomial has been constructed from due to
 * floating-point round-off.
 *
 * @param roots an array of roots
 *
 * @example
 * ```typescript
 * fromRoots([1,2,3,3]); //=> [1, -9, 29, -39, 18]
 * allRoots([1, -9, 29, -39, 18]); //=> [1.0000000000000007, 2.000000000000004]
 *
 * // In the above note the rounding error. Also note the multiple root of 3 that has been missed.
 * allRoots([1, -9, 29, -39, 17.99999999999999]); //=> [0.9999999999999973, 2.00000000000002, 2.9999999999999982]
 * allRoots([1, -9, 29, -39, 17.9999999999999]); //=> [0.999999999999975, 2.0000000000000986, 2.9999997898930832, 3.0000002095475775]
