Gilles commented on MATH-989:
-----------------------------
bq. but wouldn't it require redundant storage of limits, when the class stores
it as well?
IMHO, it is beyond the role of this class to provide the proposed method.
>From the POV of the interpolator, it is an error to pass values outside the
>range (hence raising an exception is the appropriate behaviour).
Since the caller knows the valid range, it can, and should, intercept what
would be invalid calls to the library code (at the quite modest cost of storing
4 {{double}} variables).
> Allow code to avoid OutOfRangeException

> Exceptions are generally costlier than a test. In the
