Do you have an example of the input file?

Dear all,

I have to read an exponential number in fortran:

3.435335355E-02

I try to read it with a E format but It gave me some problems,

Thanks,
Albert

Dear xwb,

        366       6.0898E-03   0.000
        367       5.9922E-03   0.000
        368       5.8798E-03   0.000
        369       5.7485E-03   0.000
        370       2.1932E-02   0.000
        371       2.1872E-02   0.000
        372       2.1733E-02   0.000
        373       2.1471E-02   0.000

        379       1.7886E-02   0.000
        380       1.6991E-02   0.000

the second column sometimes has e-02 and sometime e-03 I'm trying to use e format but it gave me differents numbers do you know how can I do?

Thanks again,
albert

Albert,

Surely a free format read statement can be used here:-

Read(5,*)I,A,B

will happily read each line of your file
