Abstract
Working on any digital scale, either a computation scale or a reading/writing measurement scale, digital values must be considered as intrinsically inexact. For example, consider an electrical circuit where a voltage measured with a voltmeter is 11. 3 V and a resistance of \(50\,\Omega \) is measured with an ohmmeter. These values are obviously associated to their measurement devices, which have their corresponding errors. A priori, one can think that these measurements and errors could be represented by intervals, but these values need to be represented in a digital scale and they could be considered valid or not in accordance to a certain tolerance.
