AutoMultiplicationSymbol

is an option for objects such as Cell and Notebook that specifies when to automatically display a multiplication symbol between elements separated by whitespace that implies multiplication.

Details

  • AutoMultiplicationSymbol{cond1,…} specifies the conditions under which to automatically display a multiplication symbol.
  • Values for condi include:
  • "Functions"non-numerical functions
    "LineBreaks"hard line breaks that imply multiplication
    "Numbers"numbers and number‐like elements (such as fractions)
    "Symbols"symbols, including % and local variables
  • AutoMultiplicationSymbol{} prevents any automatically displayed multiplication symbols from appearing.
  • The multiplication operator is specified by the NumberMultiplier option. The default value is "∖[Times]".
  • The global setting for AutoMultiplicationSymbol can be changed in the Preferences dialog.

Basic Examples  (1)

Format an expression with automatic multiplication symbols:

Wolfram Language code: ExpressionCell[HoldForm[2 * 3 * 5], AutoMultiplicationSymbol -> {"Numbers"}]

Format an expression without automatic multiplication symbols:

Wolfram Language code: ExpressionCell[HoldForm[2 * 3 * 5], AutoMultiplicationSymbol -> {}]

Scope  (5)

Multiplication symbols are not inserted where explicit * or × operators are present:

Wolfram Language code: ExpressionCell[RawBoxes[RowBox[{"2", " ", "3", "*", "5", "×", "7"}]], AutoMultiplicationSymbol -> {"Numbers"}]

Automatic multiplication symbols between non-numeric functions:

Wolfram Language code: ExpressionCell[f[x] * g[x], AutoMultiplicationSymbol -> {"Functions"}]

Functions representing numeric operations will not have automatic multiplication symbols:

Wolfram Language code: ExpressionCell[Sin[x] * Cos[x], AutoMultiplicationSymbol -> {"Functions"}]

Automatic multiplication symbols at hard line breaks:

Wolfram Language code: ExpressionCell[Framed[RawBoxes[RowBox[{"(", RowBox[{"longsymbolname1", " ", "longsymbolname2"}], ")"}]], ImageSize -> 150], AutoMultiplicationSymbol -> {"LineBreaks"}]

Automatic multiplication symbols between numbers:

Wolfram Language code: ExpressionCell[HoldForm[2 * 3.5], AutoMultiplicationSymbol -> {"Numbers"}]

Numeric fractions are recognized as numbers:

Wolfram Language code: ExpressionCell[RawBoxes[RowBox[{FractionBox["1", "2"], " ", FractionBox["3", "4"]}]], AutoMultiplicationSymbol -> {"Numbers"}]

Automatic multiplication symbols between symbols:

Wolfram Language code: ExpressionCell[a * b, AutoMultiplicationSymbol -> {"Symbols"}]
