Execution tests for the 'acosh' builtin function
S is AbstractFloat, f32, f16
T is S or vecN<S>
@const fn acosh(e: T ) -> T
Returns the hyperbolic arc cosine of e. The result is 0 when e < 1.
Computes the non-negative functional inverse of cosh.
Component-wise when T is a vector.
Note: The result is not mathematically meaningful when e < 1.
