# reals(?Vars)

# EplexInstance:reals(?Vars)

Constraints Vars to the real domain for EplexInstance.

Vars
  Collection or nested collection of variables and numbers

## Description

Constrains Vars to the real domain in the eplex instance EplexInstance. Any variables that are not problem variables for EplexInstance are added to the problem, with unconstrained bounds (except by the external solver's idea of infinity).

Note that the notion of real is used here in the pure mathematical sense, where real numbers subsume the integers. If the variables are already instantiated, this call checks that the variable is instantiated to a number.

### Fail Conditions

Vars contain elements which are neither variable or number.
