Detailed Description

template<typename FP_Interval_Type, typename FP_Format>
class Parma_Polyhedra_Library::Constant_Floating_Point_Expression< FP_Interval_Type, FP_Format >

A generic Constant Floating Point Expression.

Template type parameters
  • The class template type parameter FP_Interval_Type represents the type of the intervals used in the abstract domain.
  • The class template type parameter FP_Format represents the floating point format used in the concrete domain.
Linearization of floating-point constant expressions

The linearization of a constant floating point expression results in a linear form consisting of only the inhomogeneous term $[l, u]$, where $l$ and $u$ are the lower and upper bounds of the constant value given to the class constructor.

inlinevirtual

Linearizes the expression in a given astract store.

Makes result become the linearization of *this in the given composite abstract store.

Parameters:
int_storeThe interval abstract store.
lf_storeThe linear form abstract store.
resultThe modified linear form.
Returns:
true if the linearization succeeded, false otherwise.

See the class description for an explanation of how result is computed.
