Class IntervalSize

Provides a test for whether an interval is so small it should be considered as zero for the purposes of inserting it into a binary tree. The reason this check is necessary is that round-off error can cause the algorithm used to subdivide an interval to fail, by computing a midpoint value which does not lie strictly between the endpoints.

MinBinaryExponent

This value is chosen to be a few powers of 2 less than the number of bits available in the double representation (i.e. 53). This should allow enough extra precision for simple computations to be correct, at least for comparison purposes.
Declaration
public const int MinBinaryExponent = -50
Field Value
Type Description
System.Int32

IsZeroWidth(Double, Double)

Computes whether the interval [min, max] is effectively zero width. I.e. the width of the interval is so much less than the location of the interval that the midpoint of the interval cannot be represented precisely.
Declaration
public static bool IsZeroWidth(double min, double max)
Parameters
Type Name Description
System.Double min
System.Double max
Returns
Type Description
System.Boolean
