Those are just a few of the things that I have had to use modulus for in my programming of not just desktop applications, but in robotics and simulation environments. The reason that it is n = (n + variable) % (listString.maxIndex + 1) is to allow for the max index to be accounted. N = (n + variable) % (listString.maxIndex + 1) Function increase Or Decrease(variable As Integer) As Void Imagine a function where you are looping through an array. For fixed-point or integer input arguments, the output data type is the aggregate type of both input signedness, word. This function is often called the modulo operation, which can be expressed as m x - floor (x./y).y.
MODULUS OPERATOR FREEMAT MOD
You want to loop up to the bottom or top of the list respectively. m mod (x,y) returns the modulus after division of x by y, where x is the dividend and y is the divisor. The elements of the array are all printed in the for loop, but every time the. count 6 divides 6 out of count as many times as it can and gives you a remainder from 0 to 5 (These are all the possible remainders because you already divided out 6 as many times as you can). In your example: 5 divided by 7 gives 0 but it remains 5 ( 5 7 5 ). You can think of the modulus operator as giving you a remainder. For instance, 9 divided by 4 equals 2 but it remains 1. This would be more work and, if 7 1 is represented to a finite number of digits, less accurate. The Modulus is the remainder of the euclidean division of one number by another. The solution is not ordinarily obtained by computing the inverse of 7, that is 7 1 0.142857., and then multiplying 7 1 by 21. The solution is easily obtained by division: x 21/7 3.
whole Number = numerator/divisorĪnother case where modulus division is useful is if you are increasing or decreasing a number and you want to contain the number to a certain range of number, but when you get to the top or bottom you don't want to just stop. The equation has the unique solution x 3. COLON Index Generation Operator - FreeMat - SourceForge. So you can be really crazy and let's say that you want to allow the user to input a numerator and a divisor, and then show them the result as a whole number, and then a fractional number. When using the modulus operator, the remainder of What does a double colon mean in math. Modulus is also very useful if for some crazy reason you need to do integer division and get a decimal out, and you can't convert the integer into a number that supports decimal division, or if you need to return a fraction instead of a decimal.
