NegativeIntegers

NegativeIntegers

represents the domain of strictly negative integers, as in xNegativeIntegers.

Details

  • xNegativeIntegers evaluates immediately if x is a numeric quantity.
  • Simplify[exprNegativeIntegers,assum] can be used to try to determine whether an expression is a negative integer under the given assumptions.
  • (x1|x2|)NegativeIntegers and {x1,x2,}NegativeIntegers test whether all xi are negative integers.
  • NegativeIntegers is output in StandardForm or TraditionalForm as TemplateBox[{}, NegativeIntegers]. This typeset form can be input using nints.

Testing membership in the negative integers is a fast way to verify negativity of a large list of integers:

Properties & Relations  (3)

Membership in NegativeIntegers is equivalent to membership in Integers along with negativity:

NegativeIntegers is contained in NegativeReals and NegativeRationals:

NegativeIntegers is disjoint from NonPositiveIntegers and PositiveIntegers:
