I’ve been trying to make an array of rationals using the @variable macro in JuMP, but I can’t seem to find out how to constrain the array to only rational values. Does JuMP allow you to build variables with Rational type? If so, how? And if not, is there an alternative?

[image] mtanneau: The only exception are a handful of LP solvers, e.g., SoPlex (also see here ) that can return exact solutions (using Rational arithmetic) to linear programming and quadratic programming problems. That functionality, however, is not available from Julia. Just to add in the par…

No. JuMP only supports Float64 variables (although you an constrain them to take binary or integer values).
