How to upload a csv excel file with full of real values

Hello I am able to do csvread('results.csv') which reads the values from the corresponding file. It works well with integers. However, when I try to upload a file with real values such 123.124, then it gives the following error:

    ??? Error using ==> dlmread at 145
    Mismatch between file and format string.
    Trouble reading number from file (row 1, field 147) ==> nit

    Error in ==> csvread at 52
        m=dlmread(filename, ',', r, c);

    Error in ==> ILJvsOJS at 12
    csvread('results9.csv');

Thank you for your help.
