⟍

mathematical falling diagonal

Mathematical falling diagonal

⟍ is a diagonal stroke for mathematical notation, running from upper left to lower right. It looks like a backslash, but it is a separate character made for mathematical typesetting. Use it for the mathematical diagonal; replacing a keyboard backslash with it can break code or file paths.

Text symbol

What ⟍ means

The stroke goes downward as you follow it rightward. “Falling” describes its direction, not a falling number or a subtraction operation. Its rising partner, , runs the other way.

The pair was designed to represent mathematical diagonal strokes in plain text as well as in typeset formulas. The intended slope of ⟍ is 135 measured counterclockwise from the rightward horizontal—visually, a 45 downward slant. The exact drawing still depends on the font.

Set Minus

Set minus: removes the members of one set from another. That operator has a different role from a diagonal stroke.

╲

Box Drawings Light Diagonal Upper Left To Lower Right

A box-drawing diagonal, used to build text drawings. Its angle follows the font’s character-cell proportions rather than the mathematical diagonal’s intended 135°.

Reverse Solidus

The ordinary keyboard backslash, used in code and file paths. ⟍ is not an interchangeable spelling of it.

Questions people ask

Why does ⟍ show as a box on some devices?

Not every system ships a font for the Miscellaneous Mathematical Symbols-A block. Where none is installed, the character shows as an empty box; adding a font such as Noto fixes it. The character itself is still correct and copies correctly.

LaTeX

Use \diagdown in math mode with a supporting package such as amssymb. This typesets the symbol rather than inserting a plain-text character.
