	On Intel CPUs, this method enables the SSE flush-to-zero and denormalised-are-zero modes.
static bool JUCE_CALLTYPE	areDenormalsDisabled () noexcept
	This method returns true if denormals are currently disabled.

Member Functions

convertFixedToFloat() [1/2]

void JUCE_CALLTYPE juce::FloatVectorOperations::convertFixedToFloat ( float * dest, const int * src, float multiplier, int num )

staticnoexcept

References JUCE_CALLTYPE.

convertFixedToFloat() [2/2]

void JUCE_CALLTYPE juce::FloatVectorOperations::convertFixedToFloat ( float * dest, const int * src, float multiplier, size_t num )

staticnoexcept

References JUCE_CALLTYPE.

enableFlushToZeroMode()

void JUCE_CALLTYPE juce::FloatVectorOperations::enableFlushToZeroMode ( bool shouldEnable )

staticnoexcept

This method enables or disables the SSE/NEON flush-to-zero mode.

References JUCE_CALLTYPE.

disableDenormalisedNumberSupport()

void JUCE_CALLTYPE juce::FloatVectorOperations::disableDenormalisedNumberSupport ( bool shouldDisable = true )

staticnoexcept

On Intel CPUs, this method enables the SSE flush-to-zero and denormalised-are-zero modes.

This effectively sets the DAZ and FZ bits of the MXCSR register. On arm CPUs this will enable flush to zero mode. It's a convenient thing to call before audio processing code where you really want to avoid denormalisation performance hits.

areDenormalsDisabled()

bool JUCE_CALLTYPE juce::FloatVectorOperations::areDenormalsDisabled ( )

staticnoexcept

This method returns true if denormals are currently disabled.
