eps, which quantifies the relative machine precision
of floating point numbers (a machine specific quantity). The syntax
for eps is:
y = eps
y = eps('double')
y = eps(X)
First form returns eps for double precision values. For most
typical processors, this value is approximately 2^-52, or 2.2204e-16.
Second form return eps for class double or single.
Third form returns distance to the next value greater than X.
