NonPositiveReals

NonPositiveReals

represents the domain of non-positive real numbers.

Details

  • xNonPositiveReals evaluates immediately if x is a numeric quantity.
  • Simplify[exprNonPositiveReals,assum] can be used to try to determine whether an expression corresponds to a non-positive real number under the given assumptions.
  • (x1|x2|)NonPositiveReals and {x1,x2,}NonPositiveReals test whether all xi are non-positive real numbers.
  • NonPositiveReals is output in StandardForm and TraditionalForm as . This typeset form can be input using npreals.
