Prefix

  • Prefix[ f [ expr ]] prints with f [ expr ] given in default prefix form: f @ expr.
  • Prefix[ f [ expr ], h ] prints as hexpr.
  • Prefix[ expr , h , precedence , grouping ] can be used to specify how the output form should be parenthesized.
  • See the notes for Infix about precedence and grouping.
  • See the Mathematica book: Section 2.8.16.
  • See also: Infix, Postfix.
