Macro Definition Documentation

◆ JUCE_UNDENORMALISE

#define JUCE_UNDENORMALISE ( x ) { (x) += 0.1f; (x) -= 0.1f; }

This macro can be applied to a float variable to check whether it contains a denormalised value, and to normalise it if necessary.

On CPUs that aren't vulnerable to denormalisation problems, this will have no effect.
