How to threat values after ConvertAudioToFloat conversion, dynamic, instead, values

What is quot;Float Audioquot;? What is acceptable range for it?

Audio data stored a set of IEEE 32 bit floating point values instead of 16 bit signed integers.

In Avisynth the conversion from 16 bit to float is
Code:
F32=I16/32768.0
and from float to 16 bit is
Code:
I16=Saturate_int16(F32*32768.0)
The value 1.0 is normally consider 0dbm.

The range is the normal range of an IEEE floating point number, i.e. approx 1.176e-38 to 3.4e+38 a dynamic range of some 1500db (note the range of 32bit int is aprox 186db, 24bit int is approx 138db, 16bit is 90db and 8bit int is 42db)

Exactly! To put it simple:

* Range is scaled to -1.0 to 1.0
* Values outside the range are perfectly valid, but will be clipped when converting to 8/16/24/32 bit ints for output.
