A generic Opposite Floating Point Expression.
FP_Interval_Type represents the type of the intervals used in the abstract domain.FP_Format represents the floating point format used in the concrete domain.Let
be an interval linear form and let
be a sound unary operator on linear forms such that:
Given a floating point expression
and a composite abstract store
, we construct the interval linear form
as follows:
|
inlinevirtual |
Linearizes the expression in a given astract store.
Makes result become the linearization of *this in the given composite abstract store.
| int_store | The interval abstract store. |
| lf_store | The linear form abstract store. |
| result | The modified linear form. |
true if the linearization succeeded, false otherwise.Note that all variables occuring in the expression represented by operand MUST have an associated value in int_store. If this precondition is not met, calling the method causes an undefined behavior.
See the class description for a detailed explanation of how result is computed.
