I was trying other ways I did change that to 0 but still the same.
This is what is coming out the serial port.

The baud rate is set to 9600 on the serial monitor,
Now this is a strange thing I tried this code below with the ADC routine removed and to make things more simpler.
#include <LiquidCrystal.h>// Highlight out when ready to use mian display
LiquidCrystal lcd(2, 4, 5, 3, 7, 8);
const byte numChars = 10; //Number of bits to get
float resistance = 12.36;
double floatVal = 23.01;
String stringVal = ""; //data on buff is copied to this string
typedef struct Data_struct {
int PRO3600_Disconnected = 10;
boolean No_data ;
char receivedChars[numChars]; // an array to store the received data
} Data_struct;
Data_struct myData;
void setup()
{
Serial.begin(9600);
lcd.begin(8, 2);
lcd.clear();
resistance = resistance - 40.36;
dtostrf(floatVal, 10, 2, myData.receivedChars); //4 is mininum width, 4 is precision; float value is copied onto buff
Serial.print("charVal: ");
for (int i = 0; i < sizeof(myData.receivedChars); i++)
{
Serial.print(myData.receivedChars[i]);
}
Serial.println();
dtostrf(resistance, 6, 2, myData.receivedChars); // L
Serial.print("dtstore: ");
Serial.print( myData.receivedChars[0]); //display string
Serial.print( myData.receivedChars[1]); //display string
Serial.print( myData.receivedChars[2]); //display string
Serial.print( myData.receivedChars[3]); //display string
Serial.print( myData.receivedChars[4]); //display string
Serial.print( myData.receivedChars[5]); //display string
Serial.print( myData.receivedChars[6]); //display string
}
void loop()
{
lcd.setCursor(0, 0);
lcd.print(resistance);
lcd.setCursor(0, 1);
lcd.print(myData.receivedChars[0]); //display string
lcd.print( myData.receivedChars[1]); //display string
lcd.print( myData.receivedChars[2]); //display string
lcd.print( myData.receivedChars[3]); //display string
lcd.print( myData.receivedChars[4]); //display string
lcd.print( myData.receivedChars[5]); //display string
lcd.print( myData.receivedChars[6]); //display string
}
This is what I get on the Serial monitor
charVal: 23.01
dtstore: -28.00
Not sure why it does or will not work when I just add this to the code in post 17.
I've just added this to the code from post 17 and get the same results.
dtostrf(stored2, 6, 2, myData.receivedChars); // L
Serial.print("dtstore: ");
Serial.print( myData.receivedChars[0]); //display string
Serial.print( myData.receivedChars[1]); //display string
Serial.print( myData.receivedChars[2]); //display string
Serial.print( myData.receivedChars[3]); //display string
Serial.print( myData.receivedChars[4]); //display string
Serial.print( myData.receivedChars[5]); //display string
Serial.print( myData.receivedChars[6]); //display string
