The f90 command is an update to the original maxima fortran command. The primary difference is the way long lines are broken.
In the next example, notice how the fortran command breaks lines within symbols. The f90
command never breaks within a symbol.
(%i1) load("f90")$ (%i2) expr:expand((xxx+yyy+7)^4); 4 3 3 2 2 (%o2) yyy + 4 xxx yyy + 28 yyy + 6 xxx yyy 2 2 3 2 + 84 xxx yyy + 294 yyy + 4 xxx yyy + 84 xxx yyy 4 3 2 + 588 xxx yyy + 1372 yyy + xxx + 28 xxx + 294 xxx + 1372 xxx + 2401 (%i3) fortran(expr); yyy**4+4*xxx*yyy**3+28*yyy**3+6*xxx**2*yyy**2+84*xxx*yyy**2+294*yy 1 y**2+4*xxx**3*yyy+84*xxx**2*yyy+588*xxx*yyy+1372*yyy+xxx**4+28* 2 xxx**3+294*xxx**2+1372*xxx+2401 (%o3) done (%i4) f90(expr); yyy**4+4*xxx*yyy**3+28*yyy**3+6*xxx**2*yyy**2+84*xxx*yyy**2+294* & yyy**2+4*xxx**3*yyy+84*xxx**2*yyy+588*xxx*yyy+1372*yyy+xxx** & 4+28*xxx**3+294*xxx**2+1372*xxx+2401 (%o4) done
The f90
implementation was done as a quick hack. It is not a
necessarily a good example upon which to base other language
translations.
To use this function write first load("f90")
.
