arithmetic_tolerance
A secondary rounding tolerance used for post-processing
Specification
Alias: None
Arguments: REAL
Default: 1.e-10
Description
After forming one or more function train approximations, this
tolerance is used for rolling up final results, in particular,
combining multilevel/multifidelity expansions and forming products for
higher-order moment estimation. It is generally intended as a looser
tolerance than rounding_tolerance.
Default Behavior
If this tolerance is not specified, then we adopt the internal C3 default.
