Hi Christian, I believe the... const v4i vRes = (v4i) v; ...will do a memcpy, not a float to int conversion. If you change it to... const v4i vRes = v; ... you get error: cannot convert 'const float __vector__' to 'const int __vector__' in initialization I think your big hammer cast is hiding the problem. Your %d output is the int32 values of the bit patterns of the float32 values. HTH, --Eljay
