(byte) 1109876546299.12334 == -1 Why?

stack overflow According to this link a conversion from a floating point number to a non-floating point number takes 2 steps: 1) the floating point number is converted to a long IF your cast is to a long, or to an int in all other cases. 2) the result of step one is then cast to your final type. When a floating point number being cast is larger than an int can hold then the result will be the max value of an int. Alternatively, when smaller, it will be set to the smallest value an int can hold. So, in this code, line 13 is a floating point number being cast to a byte. Step one says that the floating point value is first cast to an int. Because the value is greater than what an int can hold the result will be the max value of an int. Step 2 casts this to a byte, which will result in -1. Some code to consider:

public static void main(String[] args) {
   int intVal = (int) 110_987_654_6299.123_34;
   long longVal = (long) 110_987_654_6299.123_34;
   System.out.println("The cast to int results in: " + intVal);
   System.out.println("The cast to long results in: " + longVal);

   System.out.println("Casting the intVal to a byte: " + (byte) intVal);
   System.out.println("Casting the longVal to a byte: " + (byte) longVal);
}

See the results.
