Specifiying the seed will make sure the generated random number sequence is deterministic. || + ||double ||rand(), rand(int seed) ||Returns a random number (that changes from row to row) that is distributed uniformly from 0 to 1. Specifiying the seed will make sure the generated random number sequence is deterministic. || ||double ||exp(double a) ||Returns e^a where e is the base of the natural logarithm || ||double ||ln(double a) ||Returns the natural logarithm of the argument || ||double ||log10(double a) ||Returns the base-10 logarithm of the argument ||
