Detailed Description

Class representing the expression for exponential.

Roughly speaking, floating point arithmetic allows to represent positive real numbers between $10^{-307}$ and $10^{+308}$, which corresponds to a range between $e^{-707}$ and $e^{709}$. Make sure that the value of the expression of exp does not lie outside the range [-707,709]. Example:

1 P = exp(V1) / (exp(V1) + exp(V2))
