hi

i have a question
i have in a txt file some data
48883 149.55579541 12.44483936
.... .... ....
when i read a entire line
line=''
readf,1,line
print,line
i get a good output
48883 149.55579541 12.44483936

but when i read data like this
ttab = MAKE_ARRAY(nlines,3,/DOUBLE)
...
FMTp='(I5,2X,D13.8,2X,D13.8)'
for i=1,nlines do begin
READF,1,FORMAT=FMT,l1,l2,l3
ttab[i-1,0]=l1 & ttab[i-1,1]=l2 & ttab[i-1,2]=l3
endfor
and i print them
print,FORMAT=FMTp,ttab[0,0], ttab[0,1],ttab[0,2]
i get
48883 149.55580139 12.44483948
and this is not the same it should be
48883 149.55579541 12.44483936
