any of you knows how can I check if the division remainder is integer or zero?

```if ( integer ( 3/2))
```

You should use the modulo operator like this

```// a,b are ints
if ( a % b == 0) {
// remainder 0
} else
{
// b does not divide a evenly
}
```

Documentation Xcode 9.0+ For two finite values x and y , the remainder r of dividing x by y satisfies x == y * q + r , where q is the integer nearest to x / y . If x / y is exactly halfway between two integers, q is chosen to be even. Note that q is  For two finite values x and y, the remainder r of dividing x by y satisfies x == y * q + r, where q is the integer nearest to x / y. If x / y is exactly halfway between two integers, q is chosen to be even.

It sounds like what you are looking for is the modulo operator `%`, which will give you the remainder of an operation.

```3 % 2 // yields 1
3 % 1 // yields 0
3 % 4 // yields 1
```

However, if you want to actually perform the division first, you may need something a bit more complex, such as the following:

```//Perform the division, then take the remainder modulo 1, which will
//yield any decimal values, which then you can compare to 0 to determine if it is
//an integer
if((a / b) % 1 > 0))
{
//All non-integer values go here
}
else
{
//All integer values go here
}
```

Walkthrough

```(3 / 2) // yields 1.5
1.5 % 1 // yields 0.5
0.5 > 0 // true
```

truncatingRemainder(dividingBy:), Please turn on JavaScript in your browser and refresh the page to view its content. Documentation Xcode 9.0+. Framework The remainder of this value divided by other using truncating division. Discussion. Performing truncating division with floating-point values results in a truncated integer quotient and a remainder. %REM returns the remainder that results from dividing operands n by m. The two operands must be numeric values with zero decimal positions. If either operand is a packed, zoned, or binary numeric value, the result is packed numeric. If either operand is an integer numeric value, the result is integer. Otherwise, the result is unsigned numeric.

swift 3:

```if a.truncatingRemainder(dividingBy: b) == 0 {
//All integer values go here
}else{
//All non-integer values go here
}
```

How to calculate division remainder using modulo, Learn Swift coding for iOS with these free tutorials. Swift has a dedicated remainder operator in the form of % , and it's used to return the remainder after dividing one number wholly into another. For example, 14 Hacking with Swift is sponsored by Gold Supporters on Patreon – click here to find out more. The remainder is thus: 42 - 4 * 10 = 2. The remainder operator may be useful for the following problems: Test if an integer is (not) divisible by another number: x % 4 == 0 // true if x is divisible by 4 x % 2 == 0 // true if x is even number x % 2 != 0 // true if x is odd number Since 0 === -0, this also works for x <= -0.

You can use the below code to know which type of instance it is.

```var val = 3/2
var integerType = Mirror(reflecting: val)

if integerType.subjectType == Int.self {
print("Yes, the value is an integer")
}else{
print("No, the value is not an integer")
}
```

let me know if the above was useful.

The quotient remainder theorem (article), When we want to prove some properties about modular arithmetic we often make use of the quotient remainder theorem. Given any integer A, and a positive integer B, there exist unique integers Q and R such that When we divide A by B in long division, Q is the quotient and R is the remainder. iOS app · Android app  Remainder, 55 ÷ 9 can also write as 9) 55 ( or 9) 55 . Note: dividend = divisor × quotient + remainder. The dividend, divisor, quotient and remainder will help us to verify the answer of division. Add remainder (if any) with the product of divisor and quotient. The sum we get should be equal to the dividend.

Swift 5

```if numberOne.isMultiple(of: numberTwo) { ... }
```

Swift 4 or less

```if numberOne % numberTwo == 0 { ... }
```

Division (whole and remainder), Remainder. Float. Return Value. Integer. Returns the number of times Divisor will go into Dividend (i.e., Dividend divided by Divisor), as well as the remainder  Euclidean division of polynomials is very similar to Euclidean division of integers and leads to polynomial remainders. Its existence is based on the following theorem: Given two univariate polynomials a(x) and b(x) (with b(x) not the zero polynomial) defined over a field (in particular, the reals or complex numbers), there exist two polynomials q(x) (the quotient) and r(x) (the remainder

How to Get a Remainder in Your Calculator, Find the remainder of a division problem with your calculator, by working the division as usual. You'll get a decimal answer – that's fine. Subtract the Integer. In integer division and modulus, the dividend is divided by the divisor into an integer quotient and a remainder. The integer quotient operation is referred to as integer division, and the integer remainder operation is the modulus.   Discussion. By the time we reach adulthood, we normally think of division as resulting in an answer that

Program to find Quotient And Remainder in Java, The remainder is the integer left over after dividing one integer by another. The quotient is the quantity produced by the division of two numbers. For example,. (7​/2) = 3. In the ankita_chowrasia. Check out this Author's contributed articles. The modulo division operator produces the remainder of an integer division. ios operator() function in C++11 with Examples See your article appearing on the

remainder - C++ Reference, The remainder of dividing the arguments. printf */ #include <math.h> /* remainder */ int main () { printf ( "remainder of 5.3 / 2 is %f\n" , remainder (5.3,2) ); printf  ; remainder is 0; problem: but remainder is not correctly validated. Am i wrong somewhere bits 16 org 0x7c00 start: jmp demo demo: xor dx, dx mov ax, 0x0410 ; 1040 mov bx, 0x0010 ; 16 div bx mov ah, 0x000e int 0x10 mov ax, dx cmp al, 0x0030 je yes mov al, 'n' mov ah, 0x000e int 0x10 jmp \$ yes: mov al, 'y' mov ah, 0x000e int 0x10 times 510

• Use `%` modulo division, which gives the remainder.
