I don't know about an expected distribution of distribution of arguments to sinh. From glancing through research papers though, I get the sense that the [-2^(-28), 2^(-28)] range isn't used all that much. A couple of papers showing this are linked below. 1. [An Analysis of the Hyperbolic Bid Stacking Technique's Use in Modeling Power Prices](https://dl.acm.org/doi/10.1145/3640115.3640182) 2. [Experimental Validation of a 3GPP compliant 5G-based Positioning System](https://dl.acm.org/doi/10.1145/3636534.3697324) I think the [-2^(-28), 2^(-28)] range isn't all that interesting for sinh anyway as it just returns the input itself. So, I doubt any applications are relying all that heavily on it. ------------- PR Comment: https://git.openjdk.org/jdk/pull/26152#issuecomment-3046818744
