NonNegativeReals

NonNegativeReals

represents the domain of non-negative real numbers.

Details

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