Hi guys,
I have to output data to be read by other mathematica-agnostic
programs - so I wanted to avoid exponential/scientific notation if
possible.

I wrote:
nf[x_] := NumberForm[N[x], Infinity, ExponentFunction -> (Null &)]

to convert my data, but I wanted to know if I could even avoid to
write everywhere:
Write[f,nf[a],nf[b],...]

and just let Math know that it has to use nf[] as a wrapper.
Unfortunately,
f = OpenWrite["test.dat",  FormatType -> nf]

doesnt work:
FormatType::ftype: Value of option FormatType -> nf is not valid.

$printForms reports:
{InputForm, OutputForm, TextForm, CForm, FortranForm, MathMLForm, \
TeXForm, StandardForm, TraditionalForm}

any hint?
