# isMultiple(of:)

Returns true if this value is a multiple of the given value, and false otherwise.

## Declaration

```swift
func isMultiple(of other: Self) -> Bool
```

## Parameters

- `other`: The value to test.

## Discussion

Discussion For two integers a and b, a is a multiple of b if there exists a third integer q such that a = q*b. For example, 6 is a multiple of 3 because 6 = 2*3. Zero is a multiple of everything because 0 = 0*x for any integer x. Two edge cases are worth particular attention: x.isMultiple(of: 0) is true if x is zero and false otherwise. T.min.isMultiple(of: -1) is true for signed integer T, even though the quotient T.min / -1 isn’t representable in type T.
