The internal waveforms of the class Oscillator produces the wrong amplitude when the input is a negative phase. When doing PM or FM, negative phases may occur. When a negative phase is e.g. passed to the the saw sample, it produces values less than -1.0, hence going out of range. Converted all fraction calls to absFraction calls. Removed the +2 in the function Oscillator::recalcPhase. The comment here was that it was needed to avoid negative phases in case of PM. But by converting fraction to absFraction in the waveforms, negative phases are not an issue anymore. On top of that the m_phase variable gains about 2 extra bits in precision. As side effect of that, it improves the behaviour of the issue #2047 - TripleOscillator: Oscillators are getting out of sync. Though I did not investigate it thoroughly over different notes and samplerates. Add documentation to the fraction and absFraction functions in lmms_math.h as it was not immediately clear by the name what the functions do. Correct the implementation of the functions in case the flag __INTEL_COMPILER is set. (floorf rounds always down).

What is LMMS?
LMMS is a free cross-platform alternative to commercial programs like FL Studio®, which allow you to produce music with your computer. This includes the creation of melodies and beats, the synthesis and mixing of sounds, and arranging of samples. You can have fun with your MIDI-keyboard and much more; all in a user-friendly and modern interface.
