represents the range of values between min and max.

represents the union of the ranges min1 to max1, min2 to max2, .


  • You can perform arithmetic and other operations on Interval objects.
  • Interval[{min,max}] represents the closed interval that includes both end points.
  • Min[interval] and Max[interval] give the end points of an interval.
  • For approximate machine or arbitraryprecision numbers x, Interval[x] yields an interval reflecting the uncertainty in x.
  • In operations on intervals that involve approximate numbers, the Wolfram Language always rounds lower limits down and upper limits up.
  • Interval can be used as a geometric region.
  • Interval can be generated by functions such as Limit.
  • Relational operators such as Equal and Less yield explicit True or False results whenever they are given disjoint intervals.
