Description

An Equation is a formal mathematical equation (with an optional rather than required title).

If the MathML Module is used, Equation can also contain the mml:math element.

Processing expectations

Formatted as a displayed block. For an inline equation, use InlineEquation.

Processing systems that number equations or build a table of equations at the beginning of a document may have difficulty correctly formatting documents that contain both Equations with Titles and Equations without Titles. You are advised to use InformalEquation for equations without titles.

Attributes

floatstyle

Specifies style information to be used when rendering the float
