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....
