 ### Investigating rounding of real numbers
 This problem (from Microsoft's [Z3 tutorials](https://microsoft.github.io/z3guide/docs/theories/Arithmetic)) uses mixed integer and real variables to figure out whether there exists a constant `a` and two real numbers `xR` and `yR` such that `round(xR) +  round(yR)  > a` while `xR + yR < a`.
