doc = DocumentManager.Instance.CurrentDBDocument
docUnitType = doc.GetUnits().GetFormatOptions(SpecTypeId.Length).GetUnitTypeId()

if docUnitType.TypeId == UnitTypeId.FeetFractionalInches.TypeId:
    result = "Fractional"
elif docUnitType.TypeId == UnitTypeId.FractionalInches.TypeId:
    result = "Fractional"
else:
    result = "Decimal"
