Parameters

index

Type: SystemInt32
An int representing the (0-based) index of the root whose error status is to be returned.

Return Value

Type: Boolean
A bool representing the error status on the index-th root.

It is false if the approximation of the index-th root has been carried out successfully, for example, the computed approximation can be viewed as the exact root of a slightly perturbed polynomial. It is true if more iterations are needed for the index-th root.
