§ anonymous enum

anonymous enum

Enumerator
IsComplex	stan::math::var is not complex.
IsInteger	stan::math::var is not an integer.
IsSigned	stan::math::var is signed.
RequireInitialization	stan::math::var does not require initialization.
ReadCost	Twice the cost of copying a double.
AddCost	This is just forward cost, but it's the cost of a single addition (plus memory overhead) in the forward direction.
MulCost	Multiply cost is single multiply going forward, but there's also memory allocation cost.

Member Function Documentation

§ digits10()

static int Eigen::NumTraits< stan::math::var >::digits10 ( )

inlinestatic

Return the number of decimal digits that can be represented without change.

Delegates to std::numeric_limits<double>::digits10().

Definition at line 79 of file Eigen_NumTraits.hpp.

§ dummy_precision()

static stan::math::var Eigen::NumTraits< stan::math::var >::dummy_precision ( )

inlinestatic

Return the precision for stan::math::var delegates to precision for douboe.

Returns: precision
