Manometer question

Projects Programming

Hi guys! New here in the forums and new with the arduino, so i got a question for you.
I have an Manometer program that i did for arduino, that converts analog to int type 10 bits, but now i want to reverse the function, how do i do that with this program?
#define INTERVAL 1000
int x;
int timestamp;
float TEN2FLOAT (int val) {
return (val*5.0)/1023.0;
}

void metodo2(){

}
void VOLTMETER() {
x = analogRead(A0); //Lê os valores analogicos
if (millis() - timestamp < INTERVAL)
return;
else {
timestamp = millis();
Serial.print(timestamp);
Serial.print(" , ");
Serial.println(TEN2FLOAT(x), 3);
};
}

void MANOMETER(){
x = analogRead(A0); //Lê os valores analogicos
if (millis() - timestamp < INTERVAL)
return;
else {
timestamp = millis();
Serial.print(timestamp);
Serial.print(" , ");
Serial.println(TEN2FLOAT(x));

}
}

void setup() {
Serial.begin(9600);
}

void loop() {
//VOLTMETER();
MANOMETER();
}

Sorry. Here it is (it has some portuguese words)

#define INTERVAL 1000
int x;
int timestamp;
float TEN2FLOAT (int val) {
  return (val*5.0)/1023.0;
}

void metodo2(){

 
}
void VOLTMETER() {
  x = analogRead(A0); //Lê os valores analogicos
  if (millis() - timestamp < INTERVAL)
    return;
  else {
    timestamp = millis();
    Serial.print(timestamp);
    Serial.print(" , ");
    Serial.println(TEN2FLOAT(x), 3);
  };
}

void MANOMETER(){
  x = analogRead(A0); //Lê os valores analogicos
  if (millis() - timestamp < INTERVAL)
    return;
  else {
    timestamp = millis();
    Serial.print(timestamp);
    Serial.print(" , ");
    Serial.println(TEN2FLOAT(x));

   }
}

void setup() {
  Serial.begin(9600);
}

void loop() {
  //VOLTMETER();
  MANOMETER();
}

I want to reconvert the digital value (int 10 bits) to float VOLTAGE between 0 and 5

6 
float voltage = 5.0*digitalValue/1024;
7

Then i do a serial print VOLTAGE right? (BTW ignore void VOLTMETER, that is from other exercise of the project)

Really, in the time it took you to post that, you could have tried it.
