I want to write a less-than-equal sign with a brace around the equal sign. Something like this, but in "nice" (at the moment, it doesn't really look as expected):

a \overset{<}{(-)} b

That should mean something like "a is less-than-equal (less-than) b".

Is there a symbol for this or is it possible to create such a symbol?

Edit: To give an example where this is useful is something like this definition (to keep things short):

  • If a is larger than (or equal to) b, we write: a >(=) b.

This is shorter than writing out both possiblies explicitly:

  • If a is larger than b, we write: a > b.
  • If a is larger than or equal to b, we write: a >= b.
  • 3
    Why not just \mathrel{({\leq})}? It's not exactly clear what a is less-than-equal (less-than) b would mean, because one is included in the other.

    What is it useful for? < implies ≤.

  • @Bernard I added an example.

    I still do not see why you don't want a simple \leq, which means exactly what's in your title.

    You can load package amssymb (i.e., \usepackage{amssymb}) and write a \leqslant b

It's not really difficult to do it:




If $a$ is larger than (or equal to) $b$, we write $a\geqp b$.


enter image description here

However you are assigning a symbol to the obscure concept of

being larger than (or equal to)

rather than explaining the usage of two symbols.

Don't do it: I'm ready to bet that your readers will not understand what you mean. Saving a few words at the expense of clarity is not worth the pain. Consider that you will be using the symbol just once.

If a is larger than b, we write a > b. We write ab to mean that a > b or a = b.

  • Nice, thank you. You are probably right that it might not be a good idea after all, but its nice to see how it could be realized.
