Всем привет! У меня есть проект под экран nextion+arduino uno+bme280

#include "NexButton.h"
#include "NexText.h"
#include "DHT.h"


#include <Wire.h>
#include <SPI.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>

#define SEALEVELPRESSURE_HPA (1013.25)

Adafruit_BME280 bme;

#define DHTPIN 2

DHT dht(DHTPIN, DHT11);
  
NexText t0 = NexText(0, 1, "t0");
NexText t1 = NexText(0, 2, "t1");
NexText t2 = NexText(0, 3, "t2");
NexText t3 = NexText(0, 4, "t3");
NexText t4 = NexText(0, 5, "t4");

char buffer[3];
char buffer1[3];
char buffer2[3];
char bufferTemp[5];
char bufferH[10];

uint8_t days,mounth,years,minutes,hours,seconds = 0;

NexTouch *nex_Listen_List[] = 
{
    NULL
};

void setup() {
  Serial.begin(9600);
  bme.begin();
  nexInit();
  days = 5;
  mounth = 0;
  minutes = 59;
  hours = 23;
  seconds = 55;
  dht.begin();
}

void date()
{
  delay(1000);
  seconds = seconds + 1;
  if(seconds >= 60)
  {
      minutes ++;
      seconds = 0;
  }
  if(minutes == 60)
  {
    minutes = 0;
    seconds = 0;
    hours ++;
  }
  if(hours == 24)
  {
    minutes = 0;
    seconds = 0;
    hours = 0;
    days = days + 1;
  }
  
}

void updateS()
{
    memset(buffer, 0, sizeof(buffer)); 
    itoa(seconds, buffer, 10);
    if (strcmp(30, buffer))
    {
        strcpy(-1, buffer); 
    }
    t0.setText(buffer);

    memset(buffer1, 0, sizeof(buffer1)); 
    itoa(minutes, buffer1, 10);
    if (strcmp(minutes, buffer1))
    {
        strcpy(-1, buffer1); 
    }
    t1.setText(buffer1);

    memset(buffer2, 0, sizeof(buffer2)); 
    itoa(hours, buffer2, 10);
    if (strcmp(0, buffer2))
    {
        strcpy(-1, buffer2); 
    }
    t2.setText(buffer2);
}

void bmeU()
{
  float h = bme.readHumidity();

  memset(bufferTemp, 1, sizeof(bufferTemp)); 
    itoa(bme.readTemperature(), bufferTemp, 10);
    if (strcmp(0, bufferTemp))
    {
        strcpy(-1, bufferTemp); 
    }
    t3.setText(bufferTemp);

    memset(bufferH, 0, sizeof(bufferH)); 
    itoa(bme.readPressure() / 100 -250, bufferH, 10);
    if (strcmp(0, bufferH))
    {
        strcpy(1000, bufferH); 
    }
    t4.setText(bufferH);
    delay(100);
}

void loop() {
  date();
    updateS();
    bmeU();
   

  Serial.println(bme.readTemperature());
  

}

Проблема заключается в том, что градусы выводятся без сотых и десятых.
