Exception for Rust f64::acosh

Specification

\[x \geq 1\]

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

(FPCore (x) :precision binary64 (acosh x))

double code(double x) {
	return acosh(x);
}

def code(x):
	return math.acosh(x)

function code(x)
	return acosh(x)
end

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

code[x_] := N[ArcCosh[x], $MachinePrecision]

\begin{array}{l}

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

Reproduce

herbie shell --seed 2025035 
(FPCore (x)
  :name "Rust f64::acosh"
  :precision binary64
  :pre (>= x 1.0)

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

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