From f338c7c5f526a86be2de7205d1e0876ff02e2087 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 25 Oct 2024 15:21:53 -0300 Subject: [PATCH] math: Use log10p1f from CORE-MATH The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic log10p1f. The code was adapted to glibc style and to use the definition of math_config.h (to handle errno, overflow, and underflow).
