To read input in x.xExx format such as that generated by Fortran programs
specify the type of data as "Real". For example, I put the following
data into the file with a title of "data.txt"
2.34E-4 9.87E15
Then I used the following Mathematica code to read it:
In[4]:= ReadList["data.txt",Real,RecordSeparators->{"\n"," "}]
15
Out[4]= {0.000234, 9.87 10 }
The E-format is not preserved, but the numbers are stored correctly for
use by Mathematica. If a given line is to go into a separate row in the
resulting list, then the option "RecordLists->True" must be used. If the
data is separated by something other than "new line" codes and "spaces,"
then the RecordSeparators list needs to be adjusted appropriately.
