## Is REM same as mod?

If both operands are positive, rem and mod give the same result. For rem, the sign of the second operand has no effect on the result. For mod, the sign of the second operand is the same as the sign of the result.

## What is the difference between REM and mod?

mod returns the difference of the first number, and the biggest integer (possibly negative) multiple of the second number that is less than the first number: rem is just the remainder.

## How do you round to 0.5 in MATLAB?

Y = round( X ) rounds each element of X to the nearest integer.

MATLAB displays the result in the Command Window. To run the function using a different run command from the list, click Run and select the desired command.

## What Is REM operator?

The rem operator gives the remainder for the regular integer division a / n that rounds towards 0 (truncated division), so a = (a / n) * n + (a rem n) .

## How do you divide integers in Matlab?

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.
