`%`

(remainder) operator

The binary, left-associative infix `%`

operator is used to get the remainder of an
integer division.

## Usage

```
Integer two = 5 % 3;
```

## Description

### Definition

The `%`

operator is defined as follows:

```
lhs.remainder(rhs);
```

See the language specification for more details.

### Polymorphism

The `%`

operator is polymorphic.
The meaning of `%`

depends on the
`Integral`

interface.

### Type

The result type of the `%`

operator is the same as the type of its right hand operand.

### Meaning of remainder for built-in types

For the built-in numeric type `Integer`

,
`%`

computes normal mathematical remainder.

Since the other built-in numeric types do not satisfy `Integral`

, the
remainder operator cannot be used on them.
