What I have tried:

{reel}   {ECHO;valReel=atof(yytext);return reel;}

in this line i tried to replace atof with atoi but it doesn't change anything; and i tried also to put a * instead of ? on this line at the end "

reel {entier}.{chiffre}*((e|E) {entier})?

" but it seems not to be working; pls hlp
