From 515e802ae20c045e5c47b400ee6ef6e92349c978 Mon Sep 17 00:00:00 2001 From: Allan Sandfeld Jensen Date: Wed, 14 Jan 2015 11:17:47 +0100 Subject: Use C++ instead of Including math.h can pollute the default namespace, and break some compilers if cmath versions of the method are declared as using. Switching to C++ math functions also greatly simplifies handling of float qreal as C++ automatically chooses the right method. [ChangeLog][QtCore][QtMath] qmath.h no longer includes math.h, so any sources depending on that indirect inclusion may fail to build.
