From 759c0b5ecf84201f36d44b4e6c46da1886d85dee Mon Sep 17 00:00:00 2001 From: Joaquim Rocha Date: Mon, 15 Nov 2010 13:46:40 +0100 Subject: Fix wrong error assumption when converting "0.0" to double The function qstrtod calls strtod without first resetting the errno but verifying it nonetheless. This could lead to situations where the errno was already set to ERANGE and hence it would mistakenly assume the conversion could not be done right.
