I know that for two numbers
y, relationships like
x < y (and
x <= y sometimes) are called inequalities. Note here, there is an order between x and y, for example (
3 < 5).
But what's the correct usage to express the relationship that two numbers are merely not equal to each other, i.e.
x <> y?
Do we also call this an "inequality" (could be confusing) or do we call this something else?
I tried to use unequality, and spell checkers always tell me it's wrong.
