Interval arithmetic for Ada is a math library that provides an implementation of intervals for Ada. It includes arithmetic and relational operations.

Examples:

Tri-state logic

The package Intervals serves as a root package and also provides tri-state logic necessary to define relational operations on intervals. The type Logical is defined as:

type Logical is (False, True, Uncertain);

The following operations are defined for Logical:

function "not" (Left : Logical) return Logical;
function "and" (Left, Right : Logical) return Logical;
function "and" (Left : Logical; Right : Boolean)
return Logical;
function "and" (Left : Boolean; Right : Logical)
return Logical;
function "or" (Left, Right : Logical) return Logical;
function "or" (Left : Logical; Right : Boolean)
return Logical;
function "or" (Left : Boolean; Right : Logical)
return Logical;
function "xor" (Left, Right : Logical) return Logical;
function "xor" (Left : Logical; Right : Boolean)
return Logical;
function "xor" (Left : Boolean; Right : Logical)
return Logical;
