- InverseLogNormal[ <Mean μ>, <Standard Devation σ>, <Probability p> ]
- Computes the inverse of cumulative distribution function of the Log-Normal distribution at
*p*, where the Log-Normal distribution is given by mean*μ*and standard devation*σ*. - In other words, it finds
*t*such that*P(X≤t)=p*, where X is a Log-Normal random variable. Probability*p*must be from [0,1].

**Example:**`InverseLogNormal[100,2,1]`

computes \infty .
