Returns the negative (additive inverse) of its argument.

| Parameter | Requirement | Description |
|---|---|---|
| T | Integral Constant | Operation's argument. |
[Note: The requirements listed in this specification are the ones imposed by the default implementation. See Numeric Metafunction concept for the details on how to provide an implementation for a user-defined numeric type that does not satisfy the Integral Constant requirements. — end note]
For any Integral Constant c:
typedef[negate](./negate.html)<c>::type r;
| Return type: |
| | Semantics: |
Equivalent to
typedef[integral\_c](./integral-c.html)< c::[value\_type](./value-type.html), ( -c::value ) > r;
|
typedef[negate](./negate.html)<c> r;
| Return type: |
| | Semantics: |
Equivalent to
struct r :[negate](./negate.html)<c>::type {};
|
Amortized constant time.
typedef[negate](./negate.html)<[int\_](./int.html)<-10> >::type r;[BOOST\_MPL\_ASSERT\_RELATION](./assert-relation.html)( r::value, ==, 10 );[BOOST\_MPL\_ASSERT](./assert.html)(( is_same< r::[value\_type](./value-type.html), int > ));
