Module: Plurimath::Formatter::Numbers::OmmlRenderer

Defined in:
lib/plurimath/formatter/numbers/omml_renderer.rb

Overview

Renders a Formatter result (FormattedNotation, FormattedNumber, or String) into an OMML element tree. Number delegates to this so the model does not carry format-specific XML construction.
