Exception for Rust f32::acosh

Specification

\[x \geq 1\]

\[\begin{array}{l} \\ \cosh^{-1} x \end{array} \]

(FPCore (x) :precision binary32 (acosh x))

float code(float x) {
	return acoshf(x);
}

function code(x)
	return acosh(x)
end

function tmp = code(x)
	tmp = acosh(x);
end

\begin{array}{l}

\\
\cosh^{-1} x
\end{array}

Reproduce

herbie shell --seed 2025017 -o generate:proofs
(FPCore (x)
  :name "Rust f32::acosh"
  :precision binary32
  :pre (>= x 1.0)

  :alt
  (! :herbie-platform default (log (+ x (* (sqrt (- x 1)) (sqrt (+ x 1))))))

  (log (+ x (sqrt (- (* x x) 1.0)))))
