Web@IanC: There is no straightforward way to do that in first-order logic because it doesn't have either of the following concepts: (1) assigning a value to a variable with an operator like =, and (2) a formula that returns an object, rather than True or False, as output. Web3 de out. de 2011 · Since the piecewise function you want is quite simple, it could also be constructed from step functions like Boole, UnitStep and UnitBox, e.g. UnitBox [ (x + 4)/2] + UnitBox [ (x - 2)/2] These are just special cases of Piecewise, as shown by PiecewiseExpand
