This is entirely accidental and unsupported and is way it acts, at
best, oddly.

(In fact no longer has any positive effect in upcoming version 2.1)

Are you mainly interested in causing the numbers in the equation 
to be formatted?

Or would you also/instead prefer me to do display the equation as
<algebra> would do it?

(For example take a look at <algebra>25*x^2*cos(2000*t + 7)</algebra>)

&format() (and &prettyprint()) right now only support pure numbers
and chemical reactions, I could add in support for formulas.
