  • x <= y or xy yields True if x is determined to be less than or equal to y.
  • yields True if the form a non-decreasing sequence.
  • xy can be entered as x <= y or x \[LessEqual] y.
  • LessEqual gives True or False when its arguments are real numbers.
  • LessEqual does some simplification when its arguments are not numbers.
  • For exact numeric quantities, LessEqual internally uses numerical approximations to establish numerical ordering. This process can be affected by the setting of the global variable $MaxExtraPrecision.
  • In StandardForm, LessEqual is printed usingĀ .
  • xy, entered as x </ y or x \[LessSlantEqual] y, can be used on input as an alternative to xy.
  • See the Mathematica book: Section 1.5.6.
