ITsTimeGetInterval Method (Double, Double)

Finds the interval in the time vector where the argument lays in between.

If argument is below the first value, 0 is returned. If argument is above last value, the length of the vector is returned.

The result is the interval number, one based, meaning that the arg fullfills:

(vector[res-1] < arg && arg <= vector[res])

Also the scale factor for interpolating is returned. For linear interpolation

arg = vector[res-1] + fraction*(vector[res]-vector[res-1])

arg = (1-fraction)*vector[res-1] + fraction*vector[res]

If arg exists in vector, the result is such that

arg = vector[res]
