Function SCIPintervalAreDisjointEps 

pub unsafe extern "C" fn SCIPintervalAreDisjointEps(
    eps: f64,
    operand1: SCIP_INTERVAL,
    operand2: SCIP_INTERVAL,
) -> c_uint

indicates whether operand1 and operand2 are disjoint with epsilon tolerance

Returns whether minimal (relative) distance of intervals is larger than epsilon. Same as SCIPintervalIsEmpty(SCIPintervalIntersectEps(operand1, operand2)).
