how to insert keypad character as 4 digit with decimal point

hello friends

just asking how can I force lcd to display a 4 digit (00.00) by default

my code let me to insert 5 digit manual with the decimal point
but I think if can make a default format with just 4 digit and the decimal point inserted by default
and with lcd display 00.00

void price(){
   lcd.clear();
   lcd.print("A4 Price:");
   lcd.setCursor(0,1);
  
   int j=0;
while(j<5){
   char customKey = myKeypad.getKey();
if (customKey == '.' || isdigit(customKey)){             // Keypad digit only
   eep1[j]=customKey;
   lcd.print(customKey);
   lcd.cursor();
   for(int n = 0; n < sizeof(eep1); n++)               // automatically adjust for number of digits
   {
    EEPROM.update(n + startingAddress, eep1[n]);        // EEPROM UPDATE TO SAVE PRICE
    }
   j++;
   }
else if(customKey=='B'){
   lcd.noCursor();
   return;
   }

if (j==5){
   lcd.clear();
   lcd.print(">> OK");
   lcd.setCursor(0,1);
   lcd.print("......Done......");
   delay(2000);
   lcd.noCursor();
  }
  }
}
    LCD.print(value/100);
    LCD.print(".");
    if (value%100 < 10)
        LCD.print("0");
    LCD.print(value%100);
