Member Function Documentation

dummy_precision()

static Real Eigen::NumTraits< stan::agrad::var >::dummy_precision ( )

inlinestatic

Return dummy precision.

Definition at line 95 of file matrix.hpp.

epsilon()

static Real Eigen::NumTraits< stan::agrad::var >::epsilon ( )

inlinestatic

Return standard library's epsilon for double-precision floating point, std::numeric_limits<double>epsilon().

Returns

Same epsilon as a double.

Definition at line 88 of file matrix.hpp.

highest()

static Real Eigen::NumTraits< stan::agrad::var >::highest ( )

inlinestatic

Return standard library's highest for double-precision floating point, std::numeric_limits<double>max().

Returns

Same highest value as a double.

Definition at line 105 of file matrix.hpp.

lowest()

static Real Eigen::NumTraits< stan::agrad::var >::lowest ( )

inlinestatic

Return standard library's lowest for double-precision floating point, &#45;std::numeric_limits<double>max().

Returns

Same lowest value as a double.
