If you want to avoid clipping, then keep the floats below (1 - 1 / (2^N)), where N is the bit depth of the output device.
If you want to maintain symmetry of synthesized waveforms, and avoid DC offset, then you should probably honor that limit on the negative excursion as well.

AudioFile supports float format for both AIFC and WAVE (and also for NeXT,
CAF).
CoreAudio considers floats to range from -1 to +1.

-1 to +1 or -1 to +0.99999?
