double RandNormal ()
 Generates a normally distributed random number with mean 0 and variance 1. More...

 
double RandNormal (const double mean, const double variance)
 Generates a normally distributed random number with specified mean and variance. More...

 
double Random ()
 Generates a uniform random number between 0 and 1. More...

 
double Random (const double lo, const double hi)
