Different result between FPU and SIMD
Something unexpected can happen when migrating legacy project about floating-point calculation...
About two years ago, I had a chance to migrate x86 based project to x64 project.
And there are not many works I had to do. Really. Because it was just a simple tool, so all I needed to do was switch the architecture of the platform, and fix some warnings come from different size of size_t.
It seems everything works fine, yet I found something works differently than before.
