pub fn ln_1pe(self) -> Self

Calculates natural \( \ln(1+e^x) \) without overflow.

pub fn sigmoid(self) -> Self

Efficient implementation of Sigmoid function, \( S(x) = \frac{1}{1 + e^{-x}} \), see Sigmoid function

pub fn rand() -> Self

Returns pseudorandom number between 0 and 1

pub fn two() -> Self

Returns 2
