Raised by Xb5.Bag.percentile/3 when linear interpolation is required but one of the
bracketing elements is not a number.
Percentile interpolation computes a weighted average between two adjacent elements. If either element is not numeric (e.g. an atom or a string), the result would be meaningless, so this error is raised instead.
Fields:
:value— the non-numeric element that caused the failure.:bracket— the full{:between, lo, hi, t}bracket in which the failure occurred.
