x<=y or x≤y
yields True if x is determined to be less than or equal to y.
yields True if the x form a nondecreasing sequence.
- x≤y 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 using ≤.
- x≤y, entered as x </ y or x∖[LessSlantEqual]y, can be used on input as an alternative to x≤y.
