promoted_numerical< T, U > Struct Template Reference

Detailed Description

template<typename T, typename U>
struct drake::geometry::promoted_numerical< T, U >

Given the two scalar types U and T, returns the most "promoted" type.

The scalars must be either double or AutoDiffXd.

This trait implicitly encodes the logic: if either B or T are AutoDiffXd, return AutoDiffXd. The logic is illustrated with this truth table:

T	U	Result
AutoDiffXd	AutoDiffXd	AutoDiffXd
double	AutoDiffXd	AutoDiffXd
AutoDiffXd	double	AutoDiffXd
double	double	double

This also includes the helper type:

template <typename T, typename U>
using promoted_numerical_t = typename promoted_numerical<T, U>::type;

#include <drake/geometry/proximity/mesh_traits.h>

Public Types
using	type = std::conditional_t< std::is_same_v< U, double >, T, U >
