N_

Positive integers

Description

N_ represents the set of positive integers.

The four basic sets are assigned to the identifiers Z_, Q_, R_, and C_ during system initialization.

The set of positive integers, too, is assigned to the identifier N_ during system initialization. It is not represented by a basic set but by the intersection of Z_ and the interval Dom::Interval([1], infinity).
