A less-than wedge with a bar beneath it, allowing equality as well.
Also known as: At most, Less than with a line under it
≤ states that the left value is smaller than or equal to the right. The bar beneath the wedge is what admits equality, and dropping it changes a statement that includes a boundary into one that excludes it.
Is encoded as U+2264 LESS-THAN OR EQUAL TO in the Mathematical Operators block.

States that the value on its left is smaller than or equal to the one on its right, so the boundary case is included.

Is written in some traditions as a wedge over a single bar and in others over a double bar, a difference of typography rather than of meaning.
Contexts: Mathematics
A horizontal wedge opening to the right, with a single short horizontal bar drawn beneath it and parallel to the writing line.
The strict inequality with a bar added to admit equality.
Converse relations, each admitting equality.
