Currently greater than and less than use ⩽ and ⩾
This is actually uncommon. HTML's "commonly used" symbols are ≤ (&leq vs &leqslant) Latex uses /leq. The germans even have a DIN standard where they set ≤ ≥ as standard.
But the most important point is: it is visually more distinguishable from < and > signs.
So I suggest using ≤ instead of ⩽
