Thus, the answer or value of this expression is 3 or the remainder part of integer division. Remember in grade school you would say, “Eleven divided by four is two remainder three.” In many programming languages, the symbol for the modulus operator is the percent sign (%). What is modulus? It’s the other part of the answer for integer division. After you divide them up with an axe, most children will not want the ¾ of a dog.
Better yet, living things like puppy dogs.
I dare you to try and chop up three cans of soup and give each kid ¾ of a can. If you do think this way, I will change my example to cans of tomato soup. Then, giving each child 2 coins and 6 pieces of eight or 2 6/8 or 2 ¾ or 2.75. Using an axe and chopping the 3 remaining coins into pieces of eight. Don’t try thinking out of the box and pretend you’re a pirate. The dollar coins are not divisible into fractional pieces. The answer is not 2 ¾ each or 2.75 for each child. How many do they each get? The answer is 2, with me still having 3 left over (or with 3 still remaining in my hand). To illustrate our example: I have 11 dollar coins to distribute equally to my 4 children. In the real world of data manipulation there are some things that are always handled in whole units or numbers (integer data type). Integer division as learned in grade school. Again, this type of division is called integer division and it is what you learned in grade school the first time you learned about division. Consider:īecause both operands are of the integer data type the evaluation of the expression (or answer) would be 2 with no fractional part (it gets thrown away). However, division, when both operands are of the integer data type, may act differently, depending on the programming language, and is called: integer division. This type of division is known as floating-point division. Discussionīy the time we reach adulthood, we normally think of division as resulting in an answer that might have a fractional part (a floating-point data type). The integer quotient operation is referred to as integer division, and the integer remainder operation is the modulus. In integer division and modulus, the dividend is divided by the divisor into an integer quotient and a remainder.
