Removing decimal places

Projects Programming

Hello, I want to remove decimals after my original number in the monitor. Is there any way I can easily integrate it with this code:

const int sensorPin = A0;

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

void loop() {
  
  int sensorVal = analogRead(sensorPin);
  float voltage = (sensorVal / 1024.0) * 5.0;
  float temperature = (voltage - .5) * 100;
  
  Serial.println("Degrees Fahrenheit:");
  float ftemp = (temperature * 9 / 5 + 32);
  Serial.println(ftemp);
  
  delay(1000);
}

My serial monitor only displays temperature values with two decimals after it. Help is appreciated!

* `Serial.print(1.23456, 0)` gives "1"

Thank you!
It worked perfectly.

1. Practically, you want to keep only the integer part of the result. So, the logical solution could be:

int iTemp = (int)ftemp;  //iTemp is in binary format and not in "floating point format"
Serial.println(iTemp);

2. Moreover, assume that your ftemp = 34.75; how much do you want to see on the output device (the Serial Monitor) -- 34 or 35?
