Der Operator % (Prozentzeichen) dient bei ganzen Zahlen dazu, den Divisionsrest zu ermitteln. Adding -3 will not work. If you want to get a negative number for negative inputs then you can use this: Likewise if you were using a language that returns a negative number on a negative input and you would prefer positive: One of the options had to be chosen by Java language developers and they chose: the sign of the result equals the sign of the dividend. This works because, if you're working modulo$7$, then adding$7$is the same as not changing the number (modulo$7\$). 27, Nov 10. For example, when 52.1 is divided by 10, the divisor (10) goes into the dividend (52.1) five times (5 * 10 == 50), and there is a remainder of 2.1 (52.1 - 50 == 2.1). I am sure you would be familiar with the term Modulus. 14. In this tutorial, we will see about XOR operator in java. In mathematics, the result of the modulo operation is an equivalence class, and any member of the class may be chosen as representative; however, the usual representative is the least positive residue, the smallest non-negative integer that belongs to that class (i.e., the remainder of the Euclidean division).
