Many indigenous African languages including Igala possess distinct numeral system that is grossly
underrepresented in contemporary computational technologies. This study focuses on the development of a
computational model for automatic conversion of English numerals to their corresponding Igala numerals. The
objectives of the study includes: digital inclusivity, language preservation and advancing research in
computational linguistics. A rule based approach was deployed to capture the structural and morphological
features of Igala language. The research methodology involved detailed analysis of the rules for the
construction of Igala numerals, system design and implementation, testing and evaluation across a wide range
of numeric values. The model was implemented using PHP, a server side scripting language, HTML, CSS as
client side scripting languages and MYSQL database as backend. The model was tested on 10,000 randomly
generated English numbers. Evaluation results showed that 99.6% accuracy was achieved, a clear indication
that the system effectively converts English numerals to correct Igala numeral forms with high accuracy
