I'm getting a divide by zero error when I use this function. It compiles fine. Since I'm not using a select statement I'm assuming NULLIF isn't going to work. What can I use to avoid the divide by zero issue?

    OPEN GET_DATA;
    fetch GET_DATA into v_gpa_hsch,v_gpa_hsch_scale,v_gpa_scale,v_gpa,
     v_gpa_recalc,v_gpa_hsch_recalc;
    IF GET_DATA%NOTFOUND
    THEN
    IT_final_final_calc :=0;

    ELSE
            IF  v_gpa_hsch_scale < v_gpa_scale
            THEN IL_higher_scale_calc := v_gpa_scale;
            ELSE IL_higher_scale_calc := v_gpa_hsch_scale;
            END IF;

            IF v_gpa_hsch < v_gpa
            THEN IM_gpa_calc := v_gpa;
            ELSE IM_gpa_calc := v_gpa_hsch;
            END …
