square() [4/7]

template<typename T , require_arithmetic_t< T > * = nullptr>

double stan::math::square ( const T  x )

inline

Return the square of the specified argument.

$\mbox{square}(x) = x^2$.

The implementation of square(x) is just x * x. Given this, this method is mainly useful in cases where x is not a simple primitive type, particularly when it is an autodiff type.

Parameters

x	Input to square.

Returns

Square of input.
