Infix Binary Operator: "=" "+" "-" "*" "/" "**" "^" (i-output.boot.pamphlet =>

  fortPre1 e ==
    -- replace spad function names by Fortran equivalents
    -- where appropriate, replace integers by floats
    -- extract complex numbers
    -- replace powers of %e by calls to EXP
    -- replace x**2 by x*x etc.
    -- replace ROOT by either SQRT or **(1./ ... )
    -- replace N-ary by binary functions
    -- strip the '%' character off objects like %pi etc..
