Unequal

• x y can be entered as x \[NotEqual] y or x y.

• lhs rhs returns True if lhs and rhs are determined to be unequal by comparisons between numbers or other raw data, such as strings.

• Approximate numbers are considered unequal if they differ beyond their last two decimal digits.

• ... gives True only if none of the are equal. 2 3 2.

• lhs rhs represents a symbolic condition that can be generated and manipulated by functions like Reduce and LogicalExpand.

• Unequal[e] gives True.

• For exact numeric quantities, Unequal internally uses numerical approximations to establish inequality. This process can be affected by the setting of the global variable $MaxExtraPrecision.

• In StandardForm, Unequal is printed using .
