Expected the outcome of the scene below to be te other way around.

---%<------%<---
#declare F=function(a){a>-1 | a<1}  //returns  0 0 1 0 0
                                    //expected 1 1 1 1 1

//#declare F=function(a){a>-1 & a<1}  //returns 1 1 1 1 1
                                    //expected 0 0 1 0 0

#debug concat(str(F(-2), 2, 0), "\n")
#debug concat(str(F(-1), 2, 0), "\n")
#debug concat(str(F( 0), 2, 0), "\n")
#debug concat(str(F( 1), 2, 0), "\n")
#debug concat(str(F( 2), 2, 0), "\n\n")
