Oh yes, i didn't realized there is something similar. However, this also adds (similar)&nbsp;&nbsp;DAZ (Denormals are Zero) flag, and resets the old behavior.&nbsp;

And&nbsp;FloatVectorOperations is maybe misleading, because the newer compilers (from VS2012, XCode) using SSE for all float-operations per default.

&nbsp;

How to check if denormals are currently used:

&nbsp;&nbsp;float f=std::numeric\_limits\<float\>::min()\*0.5f;&nbsp;

&nbsp; jassert (f==0);&nbsp;//&nbsp;you cannot do this in a one line, would be optimized away

&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; double d=std::numeric\_limits\<double\>::min()\*0.5;

&nbsp; jassert (d==0);

&nbsp;
