FortranForm
FortranForm[
expr
] prints as a Fortran language version of expr.
Standard arithmetic functions and certain control structures are translated.
FortranForm acts as a "wrapper", which affects printing, but not evaluation.
The width of output lines must be set explicitly by giving the option PageWidth
->
n for the relevant output stream.
SetOptions[$Output,
PageWidth
->
72] uses a line width of 72 characters for standard Mathematica output.
No declarations are generated.
See the Mathematica book: Section 1.11.4, Section 2.8.1.
See also: CForm, Compile.
Further Examples
The FortranForm is equivalent to the original quadratic.
