<inline-formula> Formula, Inline

Mathematical equation, expression, or formula that is to be displayed inline. The mathematics itself can be expressed as ASCII characters, as a graphic, or using TeX, LaTeX, or MathML mathematics expressions.

Usage/Remarks

Some print-oriented tag sets use a specific element to indicate “go into math mode or math font here”. While that was not the intended usage of this element, in nearly all cases the text inside such math-changes is a mathematical expression. It would not be incorrect to use this element to mark such material; however, some users may find this tagging undesirable.
Related Elements
For a mathematical equation, expression, or formula which is to displayed as a block (callout), use the <disp-formula> element.

 <p>This is the third and last part of the volume devoted to solubility data of rare 
  earth metal chlorides in water and in ternary and quaternary aqueous systems. 
  Compilations of all available experimental data for each rare earth metal chloride 
  are introduced with a corresponding critical evaluation. Every such evaluation 
  contains a tabulated collection of all solubility results in water, a scheme of the 
  water-rich part of the equilibrium

  solubility data, and a brief discussion of the multicomponent systems. Because 
  the ternary and quaternary systems were almost never studied more than once, 
  no critical evaluations or systematic comparisons of such data were possible. 
  Simple chlorides (no complexes) of Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu are treated 
  as the input substances. The literature (including a thorough coverage of papers 
  in Chinese and Russian) has been covered through the middle of 2008.</p>
