Integer Division Matlab (2025)

FAQs

Does Matlab do integer division? ›

C = idivide( A , B ) divides each element of A by the corresponding element of B , rounded to the nearest integers toward zero. A and B must contain real numbers and at least one of them must belong to an integer class.

Integer division refers to the process of dividing two integers and obtaining the quotient without any fractional part. It is a fundamental operation in computer science and is used to perform calculations that involve whole numbers.

Names and symbols used for integer division include div, /, \, and %.

Description. X = A / b performs right-matrix division. X = mrdivide( A , b ) is an alternative way to execute X = A/b .

Integer division, denoted by the "//" operator, performs division and returns the result as an integer. It discards the decimal part of the division result, giving the whole number quotient.

Division of integers means equal grouping or dividing an integer into a specific number of groups. For example, -6 ÷ 2 means dividing -6 into 2 equal parts, which results in -3. Let us learn more about the multiplication and division of integers in this article.

Java does integer division, which basically is the same as regular real division, but you throw away the remainder (or fraction). Thus, 7 / 3 is 2 with a remainder of 1. Throw away the remainder, and the result is 2. Integer division can come in very handy.

Here, 10 is a dividend, 3 is a divisor, then the quotient (solution) will be: 10/3 = 3.3333333…..

Because 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). 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.

Does integer division always round down? ›

Integer division rounds towards zero.

This means, for example, that the result of the integer division 7 / 5 would have the real number 1.4 as an intermediate result and rounded in the direction of 0 would result in 1 .

r = rem( a , b ) returns the remainder after division of a by b , where a is the dividend and b is the divisor. This function is often called the remainder operation, which can be expressed as r = a - b. *fix(a./b) . The rem function follows the convention that rem(a,0) is NaN .

div = divergence( X , Y , Fx , Fy ) computes the numerical divergence of a 2-D vector field with vector components Fx and Fy . The matrices X and Y , which define the coordinates for Fx and Fy , must be monotonic, but do not need to be uniformly spaced.

MATLAB supports 1-, 2-, 4-, and 8-byte storage for integer data. You can save memory and execution time for your programs if you use the smallest integer type that accommodates your data. For example, you do not need a 32-bit integer to store the value 100 .

Integers are closed under division, i.e. for any two integers, a and b, a ÷ b will be an integer.

x = A ./ B divides each element of A by the corresponding element of B . The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other.

Use the MOD function. It will only return ZERO (0) if and when it is divisible by the number you choose. So MOD(A,b) will only return 0 when A is an integer multiple of b.
