\ (reverse solidus)

Set the number of displayed digits of a number or the display limit of a container.

Syntax

• X \ n

  • X is a compatible object

  • n is a non-negative integer

Description

If X is a number, then X \ n returns X with its number of digit setting set to n. This is a shortcut to SetNumDigits(X, n).

If X is a suitable container, then X \ n returns X with its display limit set to n. This is a shortcut to SetMaxLen(X, n).

Notes

Don’t confuse the set minus symbol ∖ (U+2216: SET MINUS) with \ (U+005C: REVERSE SOLIDUS).
