Text Formatting ⇒ Improper Output for HTML in Math Mode

[Sundial]

Consider this example.

Code: Select all

\documentclass[a4paper,11pt] {article}
\usepackage[english]{babel}                 
\usepackage{amsmath}         
\begin{document}
$$
  \begin {array} {rl}
    \psi = & \psi_a - \dfrac{F(\psi_a)}{F'(\psi_a)}\\
      \vphantom{-}\\      
    \rm{until} & |\psi - \psi_a| < \epsilon \quad \rm{(accuracy\; desired)}      
  \end {array}              
$$
\end{document}

What happens after this command?

htlatex name "html.1.info"

The file name.html shows "accuracydesired" without space in between. Thanks for the drift.

We are in the LaTeX2e era. Hence we don't use some things any more.

• Unnumbered displayed equations are not typeset by the TeX syntax $$ … $$, but by the correct LaTeX syntax \[ … \].
• Roman typeface is not introduced by the switch \rm (which has no argument), but by \rmfamily. In this case the \text command from amsmath is more suitable.

The below example runs smooth with TeX4HT (which uses HTLaTeX). The output is attached.

Code: Select all

\documentclass[11pt,a4paper] {article}
\usepackage[T1]{fontenc}
\usepackage{amsmath}

\begin{document}
  \[
    \begin{array}{rl}
      \psi = & \psi_a - \dfrac{F(\psi_a)}{F'(\psi_a)}\\
      \vphantom{-} \\
      \text{until} & |\psi - \psi_a| < \epsilon \quad \text{(accuracy desired)}
    \end{array}
  \]
\end{document}

Oh yes, pretty suggestion! With \text{...} I'm satisfied now. Thank you very much!
