# get_min(?Var, -Lo)

Retrieve the current lower bound of Var.
*Var*
- A variable or a number
*Lo*
- Lower bound

## Description

Primitive for retrieving the lower bound of Var. Lo returns the minimum
of the variable's interval. If the variable is integer and the bound is
finite, then the bound will be returned as an integer; in all other cases
it will be returned as a float. If Var has not been declared before, it
will be turned into an unrestricted real variable. If Var is a ground
number, Lo will give an appropriate bound based on the type and value of
Var: an exact bound for floats, bounded reals and integers, and a best
safe approximation for rationals.
