Compiled (Built-in Mathematica Symbol)

Compiled is an option for various numerical and plotting functions which specifies whether the expressions they work with should automatically be compiled.

Mathematica System Setup (Mathematica Guide)

Mathematica allows convenient discovery and customization of all aspects of its system setup.

\[Sqrt] (Mathematica Character Name)

Unicode: 221A. Alias: Esc sqrt Esc. Prefix operator with built-in evaluation rules. √ x is by default interpreted as Sqrt[x]. Ctrl+@, Ctrl+2 or ∖@ yields a complete SqrtBox ...

\[Divides] (Mathematica Character Name)

Unicode: F3D0. Alias: Esc divides Esc. Infix operator with built-in evaluation rules. m∣n is by default interpreted as Divisible[n,m].

\[Equivalent] (Mathematica Character Name)

Unicode: 29E6 Alias: Esc equiv Esc. Infix operator with built-in evaluation rules. x ⧦ y is by default interpreted as Equivalent[x,y]. Not the same as \[DoubleLeftRightArrow] ...

\[GreaterSlantEqual] (Mathematica Character Name)

Unicode: 2A7E. Alias: Esc >/ Esc. Infix operator with built-in evaluation rules. x ⩾ y is by default interpreted as GreaterEqual[x,y].

\[ImplicitPlus] (Mathematica Character Name)

Unicode: F39E. Alias: Esc + Esc. Infix operator with built-in evaluation rules. Used in entering mixed fractions. x Esc + Esc y is interpreted as x+y, but Esc + Esc has ...

\[LeftCeiling] (Mathematica Character Name)

Unicode: 2308. Alias: Esc lc Esc. Matchfix operator with built-in evaluation rules. ⌈ x ⌉ is by default interpreted as Ceiling[x]. Extensible character.

\[LeftFloor] (Mathematica Character Name)

Unicode: 230A. Alias: Esc lf Esc. Matchfix operator with built-in evaluation rules. ⌊ x ⌋ is by default interpreted as Floor[x]. Extensible character.
