rand(1,1)*5+1 will produce random numbers uniformly distributed between 1 and 6; round will convert values from 1 to 1.5 to 1, and values from 1.5 to 2.5 to 2, so 1 will occur only about half as often as 2. Overall, 1 and 6 will occur only about half as often as 2, 3, 4, and 5.

my second ever pseudo random number generator (the first wasn't very random) http://en.wikipedia.org/wiki/Linear_congruential_generator

This is not two random rolls. The second number will never match the first, so the statistical distribution is not correct, although the test suite is not sophisticated enough to catch it.
