Good morning Paul
First of all, let me thanks.
The value is this one...Julian Day.
2455398.427
char buffer[20];
char *result;
float dJulianDate;
result = dtostrf(dJulianDate, 2, 5, buffer);
Serial.println(result);
lcd.printIn(result)
and on 'Screen IDE' and on 'LCD 4 bits', I have 2455398.50
Perhaps I miss wrong.
Thanks on advance
Best regards
Pedro Ferrer
