Hi, ALL:
I have a output, input format quesstion:
I output a series of data to a file with:
streamout1 = OpenWrite["afile"];
For[i=0....
Write[streamout1, expr[[i]] ];
];
Close[streamout1];
Clear[streamout1]
then the "afile" in a column format is:
0
0.1
0.2
1.1*10^-8
2.2*10^-8
3.3*10^-8
...
but when i try read the data in "afile" use:
ReadList["afile", Real]
it only read the 0, 0.1, 0.2.
it can't read the format in "*10^-8"
Now my question is:
(1). How to let the program can read "*10^-8" ?
(2). or is there a way that i can output to "afile"
in the format like "1.1e-8" that the Mathematica
can read?
Thanks very much....
