[Description]
Rounds the floating point number to 12 significant digits.

[Explanation]
round12 returns the value of the floating point argument <I>x</I> rounded
to 12 significant digits. TIOS sometimes does such rounding, for example when
TIOS updates coordinate values (xc, yc, etc.), during printing approximate
results, or when TIOS stores a value to system variables like xmin, xmax etc.
(strictly speaking, TIOS calls <A HREF="$$LINK(round12_err)">round12_err</A> instead
of round12 in such cases).
