# get_domain(?Var, -Domain)

Returns a ground representation of the current IC domain of a variable.
*Var*
- An IC variable or a number.
*Domain*
- A ground representation of the domain of Var.

## Description

If Var is a number, Domain will be unified with that number.

If Var is a real IC variable, Domain will be unified with the term
Lo..Hi where Lo and Hi are floats corresponding to the current lower
and upper bounds of Var, respectively.

If Var is an integer IC variable with no holes in its domain, Domain will
be unified with the term Lo..Hi where Lo and Hi are integers
corresponding to the current lower and upper bounds of Var, respectively.

If Var is an integer IC variable with holes in its domain, Domain will
be unified with an ordered list of integers and/or terms Lo..Hi where Lo
and Hi are integers; in this case the elements of the domain of Var are
exactly those integers appearing directly in the list or falling within
any of the intervals Lo..Hi.

### Modes and Determinism

### Fail Conditions

The initial value of DomainList fails to unify with the returned value.
### Exceptions

*(5) type error *
- Var is neither an IC variable or number.
