Module Rational

module Rational: sig .. end

Generation of rational numbers.

val create : loc:Cil_types.location ->
       ?name:string ->
       Cil_types.exp ->
       Env.t ->
       Cil_types.kernel_function -> Cil_types.term option -> Cil_types.exp * Env.t

Create a real

val init_set : loc:Cil_types.location ->
       Cil_types.lval -> Cil_types.exp -> Cil_types.exp -> Cil_types.stmt

init_set lval lval_as_exp exp sets lval to exp while guranteeing that lval is properly initialized wrt the underlying real library.

val normalize_str : string -> string

Normalize the string so that it fits the representation used by the underlying real library. For example, "0.1" is a real number in ACSL whereas it is considered as a double by libgmp because it is written in decimal expansion. In order to make libgmp consider it to be a rational, it must be converted into "1/10".

val cast_to_z : loc:Cil_types.location ->
       ?name:string -> Cil_types.exp -> Env.t -> Cil_types.exp * Env.t

Assumes that the given exp is of real type and casts it into Z

val add_cast : loc:Cil_types.location ->
       ?name:string ->
       Cil_types.exp ->
       Env.t -> Cil_types.kernel_function -> Cil_types.typ -> Cil_types.exp * Env.t

Assumes that the given exp is of real type and casts it into the given typ

val binop : loc:Cil_types.location ->
       Cil_types.binop ->
       Cil_types.exp ->
       Cil_types.exp ->
       Env.t ->
       Cil_types.kernel_function -> Cil_types.term option -> Cil_types.exp * Env.t

Applies binop to the given expressions. The optional term indicates whether the comparison has a correspondance in the logic.

val cmp : loc:Cil_types.location ->
       Cil_types.binop ->
       Cil_types.exp ->
       Cil_types.exp ->
       Env.t ->
       Cil_types.kernel_function -> Cil_types.term option -> Cil_types.exp * Env.t

Compares two expressions according to the given binop. The optional term indicates whether the comparison has a correspondance in the logic.
