Euler Integral
Euler integration was defined by Schanuel and subsequently explored by Rota, Chen, and Klain. The Euler integral of aFunction 
(assumed to be piecewise-constant with finitely many discontinuities) is the sum of
over the finitely many discontinuities of
. The 
-D Euler integral can be defined for classes of functions
. Euler integration is additive, so the Euler integral of 
equals the sum of the Euler integrals of and
