1969  * To avoid floating point but still provide a smooth distribution of bonuses,
1970  * we simply round the results of division in such a way as to "average" the
1971  * correct floating point value.
1972  *
1973  * This function has been changed.  It uses "randnor()" to choose values from
1974  * a normal distribution, whose mean moves from zero towards the max as the
1975  * level increases, and whose standard deviation is equal to 1/4 of the max,
1976  * and whose values are forced to lie between zero and the max, inclusive.
1977  *
1978  * Since the "level" rarely passes 100 before Morgoth is dead, it is very
1979  * rare to get the "full" enchantment on an object, even a deep levels.
