Ich vergass den Code zum anzeigen auf den Display:
eeprom.writefloat(3,1,b);
sleep 250;
c = eeprom.readfloat(3,1);
if b == c
{
pcflcd.goto(4,0);
//c = runden.arunden(c,2);
d=b*100;
pcflcd.zahl4n2(d);
pcflcd.goto(3,0);
e=c*100;
pcflcd.zahl4n2(e);
}
else
{
pcflcd.goto(4,0);
d=b*100;
pcflcd.zahl4n2(d);
pcflcd.goto(3,0);
e=c*100;
pcflcd.zahl4n2(e);
}
d ist dem Fall 25.26 aber e ist 25.00
wo liegt der Fehler ?
