LessEqual (<=, ≤)

x<=y or xy
yields True if x is determined to be less than or equal to y.
x1x2x3
yields True if the x_i form a nondecreasing sequence.
  • x≤y can be entered as x Esc <= Esc y or x\[LessEqual]y.
  • 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.
  • x≤y, entered as x Esc </ Esc y or x\[LessSlantEqual]y, can be used on input as an alternative to x≤y.
