From fcdf98f38c16ea5c7296b20db2e9f60e9e6ed39e Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 20 Sep 2024 23:24:45 +0000 Subject: Add tests of more strtod special cases There is very little test coverage of inputs to strtod-family functions that don't contain anything that can be parsed as a number (one test of ".y" in tst-strtod2), and none that I can see of skipping initial whitespace. Add some tests of these things to tst-strtod2. Tested for x86_64.
