From cdb46185654bbe0e9944cd66d631c1bf6235ce1c Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 6 Aug 2026 14:27:52 +0000 Subject: [PATCH] test: migrate `math/base/special/expm1rel` to ULP-based assertions Migrates the tests for `math/base/special/expm1rel` from relative tolerance (`EPS`-scaled) assertions to ULP-based assertions using `@stdlib/assert/is-almost-same-value`.
