These could be useful with fractions, where there is a significant
difference between \displaystyle and \textstyle .
e.g.
  Use  \mathsmaller  when there is a very wide numerator or denominator.
  Use  \mathlarger for a fraction in a footnote, say with superscripts
  on superscripts.

  \textstyle is a declaration, not a macro with argument.
So you probably want to delimit it as follows:

     {\textstyle\denom{D\mathsmaller{ECI}}}\;\denom{Dollars}

Of course!  Define your own pseudo-math-smallcaps:

  \DeclareRobustCommand{\mathsc}[1]{{\textstyle\parsemathsc #1 
\parseend}}
  \def\parsemathsc#1#2\parseend{\denom{\uppercase{#1\mathsmaller{#2}}}}

used as    $\mathsc{Deci}$  etc.

This is only pseudo- since only the very first letter remains at full  
size.
e.g.    $\mathsc{DECI}$ and $\mathsc{Deci}$ give the same result.

BTW,  did you try:  $\textsc{\sffamily Deci}$ ?
It gives small-caps, but in *Roman* style, not sans-serif.

This is because there is no ss-small-caps font.
viz.

\font at name ->\OT1/cmss/m/sc/6
{select font cmcsc10 at 6.0pt}



Hope this helps,
