Re: writing real numeric data to file in scientific form

[McHale, Paul]

I think what you are looking for is FortranForm[]. I use it exclusively now.

Here is writing it out and reading it back...

m=ToString@FortranForm[0.000003]
ToExpression[StringReplace[m,"e-"-> "*10^"]]

If you write your data to CSV format, it can be read back in with Scientific notation without issue. CSV format really rocks with Mathematica. I still use ToString@FortranForm[] for formatting prior to writing to CSV. On read, you will get numbers back and don't need the second line above.
