That probably isn't what you meant. The above statement is equivalent to

  assert((0 <= i) < dimension);.

In the unsigned case e.g., 0 <= i is always true, so that the above becomes

  assert(true < dimension).

What you probably meant is

  assert(0 <= i && i < dimension);

or for unsigned types

  assert(i < dimension);
