Description
Generates a random extended value from the range [0, 1] using normal distribution with a given Variance. If the variance is lower, the random values will have bigger chance of being closer to 0. The algorithm to calculate this is based on the Gaussian function.
Example
var
i: Integer;
begin
for i := 1 to 100 do
WriteLn(RandG(2));
end.
