In geometry, an enneagram (🟙 U+1F7D9) is a nine-pointed plane figure. It is sometimes called a nonagram, nonangle, or enneagon. [1] The word 'enneagram' combines the numeral prefix ennea-with the Greek suffix -gram. The gram suffix derives from γραμμῆ (grammē) meaning a line. [2]
In ambiguous contexts, the word hào (t 號, s 号, lit. "number") is added to the end of the size name to clarify the meaning. Note that the Chinese font sizes use American points; the Continental systems traditionally used the Fournier or Didot points.
A sequence of six consecutive nines occurs in the decimal representation of the number pi (π), starting at the 762nd decimal place. [ 1 ] [ 2 ] It has become famous because of the mathematical coincidence , and because of the idea that one could memorize the digits of π up to that point, and then suggest that π is rational .

In numerical analysis, given a square grid in two dimensions, the nine-point stencil of a point in the grid is a stencil made up of the point itself together with its eight "neighbors". It is used to write finite difference approximations to derivatives at grid points. It is an example for numerical differentiation.
In mathematics and computing, a radix point or radix character is a symbol used in the display of numbers to separate the integer part of the value from its fractional part. In English and many other languages (including many that are written right-to-left), the integer part is at the left of the radix point, and the fraction part at the right ...
Casting out nines is any of three arithmetical procedures: [1] Adding the decimal digits of a positive whole number , while optionally ignoring any 9s or digits which sum to 9 or a multiple of 9.
Non-printing characters or formatting marks are characters for content designing in word processors, which are not displayed at printing. It is also possible to customize their display on the monitor. The most common non-printable characters in word processors are pilcrow, space, non-breaking space, tab character etc. [1] [2]
