/**
* Fixes floating point rounding errors in a result by rounding
* to the same specificity, or number of decimal places (*not*
* significant figures) as provided reference numbers. If multiple
* references are provided, the highest number of decimal places
* between them will be used.
*
* The main use case is when numbers x and y are added to produce n,
* but x and y are floats, so n may have rounding errors (such as
* 3.1000000004 instead of 3.1). As long as only addition/subtraction
* occurs between x and y, the specificity of the result will never
* increase, so x and y should be passed in as the references.
*
* If multiplication, division, or other operations were used to
* calculate n, the rounded result may have less specificity than
* desired. For example, 1 / 3 = 0.33333(...), but
* roundToMaxDecimalPlaces((1 / 3), 1, 3) will return 0, since both
* 1 and 3 are whole numbers.
*
* Note that extremely precise reference numbers may lead to rounding
* errors not being trimmed, due to the error result having the same or
* fewer decimal places as the reference(s). This is acceptable as we
* would not be able to tell the difference between a rounding error
* and correct value in this case, but it does mean there is an implicit
* precision limit. If precision that high is needed, it is recommended
* to use a third party data type designed to handle floating point
* errors instead.
*
* @param n The number to round.
* @param references Number(s) used to calculate n, or that should otherwise
* be used as a reference for the desired specificity.
