One of the well-known examples of such spaces is the Minkowski space, which plays a leading role in the problems of the special theory of relativity and electrodynamics. However, such numbers are not very common in different programming languages. Of interest is the implementation of hyperbolic complex in scientific programming languages, in particular, in the Julia language. The Julia language is based on the concept of multiple dispatch. This concept is an extension of the concept of polymorphism for object-oriented programming languages. To implement hyperbolic complex numbers, the multiple dispatching approach of the Julia language was used. The result is a library that implements hyperbolic numbers. Based on the results of the study, we can conclude that the concept of multiple dispatching in scientific programming languages is convenient and natural.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Гиперболические комплексные числа применяются при описании гиперболических пространств. Одним из известных примеров таких пространств является пространство Минковского, играющее ведущее значение в задачах частной теории относительности, электродинамики. Однако такие числа не очень распространены в разных языках программирования. Представляет интерес реализация гиперболических комплексных чисел в языках научного программирования, в частности в языке Julia. В основе языка Julia лежит концепция множественной диспетчеризации (multiple dispatch). Эта концепция является расширением концепции полиморфизма для объектно-ориентированных языков программирования. Разработана библиотека для Julia, реализующая гиперболические комплексные числа. По результатам исследования можно сделать вывод об удобстве и естественности концепции множественной диспетчеризации в языках научного программирования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Julia programming language</kwd><kwd>multiple dispatch</kwd><kwd>abstract data types</kwd><kwd>type conversion</kwd><kwd>parametric structures</kwd><kwd>hyperbolic complex numbers</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>язык программирования Julia</kwd><kwd>множественная диспетчеризация</kwd><kwd>абстрактные типы данных</kwd><kwd>конвертация типов</kwd><kwd>параметрические структуры</kwd><kwd>гиперболические комплексные числа</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This paper has been supported by the RUDN University Strategic Academic Leadership Program.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>J.
