unary_op - Objeto función de operación unaria que se aplicará.

La signatura de la función deberá ser equivalente a lo siguiente:

 Ret fun(const Type &a);

La signatura no necesita tener const &.
El tipo Type debe ser tal que un objeto del tipo double puede ser desreferenciado y entonces convertido implícitamente a Type. El tipo Ret debe ser tal que un objeto de tipo double puede ser desreferenciado y asignado un valor de tipo Ret. ​

params -
el parámetro de distribución establecido
Original:
