| Synopsis | This function returns a random number normally distributed with average 0 and variance 1. Normal_Rand uses Rand() which can be seeded by either the function SetRand or SetRandSeed. An normal variable with average m and variance s2 is obtained with the expression sqrt(s2)*Rand(Normal) + m or with Rand(Normal(m,s2)). | ||||||||||||
