1Blurb:: A secondary rounding tolerance used for post-processing 2 3Description:: 4After forming one or more function train approximations, this 5tolerance is used for rolling up final results, in particular, 6combining multilevel/multifidelity expansions and forming products for 7higher-order moment estimation. It is generally intended as a looser 8tolerance than \c rounding_tolerance. 9 10<b> Default Behavior </b> 11 12If this tolerance is not specified, then we adopt the internal C3 default. 13 14Topics:: 15 16Examples:: 17Theory:: 18Faq:: 19See_Also:: model-surrogate-global-function_train-rounding_tolerance 20
