Hello.
I need to export to a file several numbers with a specific number of
digits on the right of the decimal. I'm trying this with the function
NumberForm[] and Export[] but the problem is that export function is
not exporting only the number but the full inputform. For example, if
I do this:
Export["teste.dat", NumberForm[1.23456, {3, 4}]]
it will write in the file this:
NumberForm[1.23456, {3, 4}]
It happens the same with:
NumberForm[1.23456, {3, 4}]>>"teste.dat".
Another problem is that in the end I need the data in fortran form,
which mean I can't pass to a string before exporting because for the
cases of raw data that are in scientific format the final result will
be a string with "10^x" which is not fortran format.
Thanks,
Miguel
