Returns the area under a Lookup table between start and end. This is useful for normalizing lookups in problems such as determining the intensity of effort in a project given the fraction of work that has been completed.
Units: LOOKUP AREA(units1,units2,units2) --> units1 * units2
Start and end must have the same units and the units of the Lookup times the units of the input are returned.
Example
LOOK((0,1),(1,1),(2,2))
LOOKUP AREA(LOOK,0,1) is equal to 1.0
LOOKUP AREA(LOOK,2,4) is equal to 4.0
LOOKUP AREA(LOOK,.5,2.5) is equal to 3.0
