# Number & Integer

Represents JS primitive type `number`.

```javascript
{
    "type": "number"
}
```

Represents integer type. Since JS doesn't have integer it's represented as JS primitive type `number`.

```javascript
{
    "type": "integer"
}
```

### Options

#### minimum

The value of "minimum" MUST be a number, representing an inclusive lower limit for a numeric instance. If the instance is a number, then this keyword validates only if the instance is greater than or exactly equal to "minimum".

#### maximum

The value of "maximum" MUST be a number, representing an inclusive upper limit for a numeric instance. If the instance is a number, then this keyword validates only if the instance is less than or exactly equal to "maximum".

### Options for only number type

#### even

The value of "even" MUST be a boolean, representing the number must be even.

#### odd

The value of "odd" MUST be a boolean, representing the number must be odd.

### Options for only number type

#### exclusiveMinimum

The value of "exclusiveMinimum" MUST be number, representing an exclusive lower limit for a numeric instance. If the instance is a number, then the instance is valid only if it has a value strictly greater than (not equal to) "exclusiveMinimum".

#### exclusiveMaximum

The value of "exclusiveMaximum" MUST be number, representing an exclusive upper limit for a numeric instance. If the instance is a number, then the instance is valid only if it has a value strictly less than (not equal to) "exclusiveMaximum".

#### minDecimalDigits

The minimum number of digits after the decimal point. Default is 0.

#### maxDecimalDigits

The maximum number of digits after the decimal point. Default is unlimited. Note: JS uses float so you do not have unlimited fractions.

### Examples

```javascript
{
    'type'            : 'number',
    'required'        : true,
    'default'         : 1,
    'minDecimalDigits': 3,
    'maxDecimalDigits': 3,
}
