Detailed Description

template<typename T = void>
struct thrust::square< T >

square is a function object. Specifically, it is an Adaptable Unary Function. If f is an object of class square<T>, and x is an object of class T, then f(x) returns x*x.

Template Parameters
Tis a model of Assignable, and if x is an object of type T, then x*x must be defined and must have a return type that is convertible to T.

The following code snippet demonstrates how to use square to square the elements of a device_vector of floats.

const int N = 1000;
thrust::sequence(V1.begin(), V1.end(), 1);
thrust::transform(V1.begin(), V1.end(), V2.begin(),
// V2 is now {1, 4, 9, ..., 1000000}
