	<P>Set the dielectric constant for Coulombic interactions (pairwise and
	long-range) to this value. The constant is unitless, since it is used
	to reduce the strength of the interactions. The value is used in the
	denominator of the formulas for Coulombic interations - e.g. a value
	of 4.0 reduces the Coulombic interactions to 25% of their default
	strength. See the <A HREF = "pair_style.html">pair_style</A> command for more
	details.
