Trait opendp::traits::arithmetic::InfExpM1

pub trait InfExpM1: Sized {
    // Required methods
    fn inf_exp_m1(self) -> Fallible<Self>;
    fn neg_inf_exp_m1(self) -> Fallible<Self>;
}

Expand description

Fallibly exponentiate and subtract one with specified rounding.

Throws an error if the ideal output is not finite or representable. This provides more numerical stability than computing the quantity outright.

Required Methods§

For any self of type Self, self.inf_exp_m1() either returns Ok(out), where $out \ge \exp(self) - 1$, or Err(e).

For any self of type Self, self.neg_inf_exp_m1() either returns Ok(out), where $out \le \exp(self) - 1$, or Err(e).
