How do you convert a float to string?

Example
Convert string to integer/ float in Arduino

void setup() {
   Serial.begin(8850);
   Serial.println();
   // put your setup code here, to run once:
   String user1 = "9856";
   String user2 = "9.56";
   String user3 = "Pakainfo";
   int res1 = user1.toInt();
   int res2 = user2.toInt();
   int res3 = user3.toInt();
   float male = user2.toFloat();
   float female = user3.toFloat();
   Serial.println(res1);
   Serial.println(res2);
   Serial.println(res3);
   Serial.println(male);
   Serial.println(female);
}
void loop() {
   // update your main source code here, to run repeatedly:
}

Converting a floating point value to a string

Example

void setup()
{
  Serial.begin(9600);
  
  float floatVal= 5689.91 ;   
  String userDataValStr = "";     
  
  userDataValStr+=String(int(floatVal))+ "."+String(getDecimal(floatVal));
  Serial.print("userDataValStr: ");Serial.println(userDataValStr);              
  
  char userCharInfo[userDataValStr.length()+1];                      
  userDataValStr.toCharArray(userCharInfo,userDataValStr.length()+1);    
  
  Serial.print("userCharInfo: ");  
  for(uint8_t i=0; i<sizeof(userCharInfo);i++) Serial.print(userCharInfo[i]); //display character array
  
}

void loop()
{

}


long getDecimal(float val)
{
 int intPart = int(val);
 long lastRes = 10 *(val-intPart); 
                                   
 if(lastRes>0)return(lastRes);           
 else if(lastRes<0)return((-1)*lastRes); 
 else if(lastRes=0)return(00);          
}
