alias:math2mathml

syntax:!mathmlmath ``expr''

mean:Translate the raw mathematical expression ``expr'', into a form which can be best \

  possibly rendered via mathml tags. The transformations\

  are the same as in htmlmath command and the result is in html if mathml is not available.\

  If the expression is not a "machine-understandable mathematical expression",\

  there is no garanty on the result (today and in the future !).\

  <ul><li>\

  All digits or + or - following a ^ or _ are considered as in exponent/subscript;\

  expression with ( ) following a ^ or _ are  considered as in exponent/subscript;\

  parentheseses are removed (if no sign before) except in case of exponent and only digits.\

  </li><li>\

   Get rid of 1*.. ..*1. example: in 1 * x, x/1, the 1 is removed.\

  </li><li>\

  Replace scientific notation (for example) 35E-05 by 10 power and add multiplication sign. Remove the + or 0 useless.\

  </li><li>\

   Replace some names as greek letters by their equivalents.\

  </li><li>\

   Remove * or replace by multiplication sign.\

  </li><li>\

   Replace <=, >=, ->, =>, <=> by their html/mathml equivalents if possible.\

  </li></ul>
