◆ cbrt()

template<typename T >
constexpr T sva::details::cbrt ( T  x)
constexpr

Constexpr version of the cubic root Return value:

  • For a finite of "x", returns an approximation for the cubic root of "x"
  • Otherwise, returns NaN
    Note
    Should not be used for value x such that x+1==x or x+1==1 in floating point arithmetic.

◆ cbrtNewtonRaphson()

template<typename T >
constexpr T sva::details::cbrtNewtonRaphson ( T  x,
T  curr,
T  prev 
)
constexpr

◆ cbrtSub()

template<typename T >
constexpr T sva::details::cbrtSub ( T  x)
constexpr

◆ dSO3JacF2()

template<typename T >
T sva::details::dSO3JacF2 ( const T &  x)
inline

Compute the value $ \frac{x + \sin(x)}{2x^2(1-\cos(x)} - \frac{2}{x^3}$ which is the derivative of $ \frac{1}{x^2} - \frac{1+\cos(x)}{2 x \sin(x)} $.

◆ eq()

template<typename T >
constexpr bool sva::details::eq ( T  x,
T  y 
)
constexpr

◆ SO3JacF2()

template<typename T >
T sva::details::SO3JacF2 ( const T &  x)
inline

Compute the value $ \frac{1}{x^2} - \frac{1+\cos(x)}{2 x \sin(x)} $.

◆ sqrt()

template<typename T >
constexpr T sva::details::sqrt ( T  x)
constexpr

Constexpr version of the square root Return value:

Note
Should not be used for value x such that x+1==x or x+1==1 in floating point arithmetic.

◆ sqrtNewtonRaphson()

template<typename T >
constexpr T sva::details::sqrtNewtonRaphson ( T  x,
T  curr,
T  prev 
)
constexpr
