# 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.
