▸ function hornerWithRunningError
(p: number[], x: number): number[]
Defined in evaluate/double/horner-with-running-error.ts:19
Returns the result of evaluating a polyniomial at a point x, including a
running error bound as an array in the form [r,e] where r is the result
of the evaluation and e is the error.
