Gaussian number distribution conforms to the standard bell curve you see in statistics class. That means that if you specify a gausian number of 10 with a standard deviation of 2, you can, and will, get numbers much greater than 12 and much less than 8. In fact, you can get numbers which approach infinity on either side. It's just much less likely that you will get numbers outside of the range 8 to 12. Since, for the purposes of your simulation, you might require your input have some minimum and maximum limit, my gaussian number representation supports this.
Gaussian numbers have many uses in games and simulations.
They are the absolute optimal numeric representation for any particle simulation, or input where you want to specify a fuzzy number instead of an exact one. The syntax for a gaussian number is in four parts. Only the first part is required, the last 3 are optional. The average deviation between the mean value. The minimum value we will allow.
