Unicode: F431. Alias: Esc == Esc. Infix operator with built-in evaluation rules. x  y is by default interpreted as Equal[x,y] or x==y. \[Equal] is drawn longer than ...

lhs == rhs returns True if lhs and rhs are identical.

Unicode: 00AC. Aliases: Esc ! Esc, Esc not Esc. Prefix operator with built-in evaluation rules. ¬ x is by default interpreted as Not[x], equivalent to !x.

! expr is the logical NOT function. It gives False if expr is True, and True if it is False.

ColumnsEqual is an option for the low-level function GridBox which specifies whether all columns in the grid should be assigned equal width.

RowsEqual is an option for the low-level function GridBox that specifies whether all rows in the grid should be assigned equal total height.

Unicode: 2260. Alias: Esc != Esc. Infix operator with built-in evaluation rules. x ≠ y is by default interpreted as Unequal[x,y].

lhs != rhs or lhs != rhs returns False if lhs and rhs are identical.

x <= y or x <= y yields True if x is determined to be less than or equal to y. x_1 <= x_2 <= x_3 yields True if the x TraditionalForm\`i form a nondecreasing sequence.

Mathematica uses a large number of original algorithms to provide automatic systemwide support for inequalities and inequality constraints. Whereas equations can often be ...
