Hi All! I am going out of head reading a formatted text file, it should not be a problem, but I am having strange issues: this is the file test ( I add a ruler ) I need to read the underlined value: AAA 2921.5 0.0000000.296018145670195E+08.............................. ----+----0----+----0----+----0----+----0----+----0----+----0...... AND THIS IS THE CODE a=0.00000000000000000000000E00 e=0.00000000000000000000000E00 i=0.00000000000000000000000E00 omega=0E00 frase='' frase1='' readf, 1 , frase1 reads, FORMAT = '(A23, E21.15,D21.15,D21.15,D21.15,D21.15,D21.15 )', frase1, frase, a , e ,i , omega, perigee , mean a1= double(STRMID(pio, 23 , 21)) print, FORMAT = '(E21.15)' , a print, FORMAT = '(E21.15)' , a1 If I print the value of a I have: 2.960181400000000E+07 that is completely wrong While if I print the value of a1 I have the right one, but this way is too tricky 2.960181456701950E+07 I also printed out the: print, FORMAT = '(E21.15)' , a mod long(a) and I obtained 0.00 !! Thank you so much for any explanation!! Ciao
