Description
Given an EvenlyDiscretizedFunction? with a single x-value (say 6.5) and a tolerance of 0.01, any call to any method relying on getXindex(x) will be fine for values <= 6.5, but will fail above, even if within tolerance.

The situation arose because both methods, in trying to determine an index, divide by 'delta', which is 0 for single valued functions resulting in attempts to round NaN, +Infinity, -Infinity;p the ultimate result was that for values > x(0), the index returned was -1. Both methods mentioned above were adjusted to handle the single-value case. This should not have adverse side effects unless there is code that unknowingly relies on the error. Fixed in [8054]
