When encoding a floating point number as a fixed point integer Q16.16 with int(number * 0x10000), what is the range of floating point that can be represented without loosing precision ?
Range is 32767 to -32768 plus or minus the fractional part at maximum. So
32767 + 65535/65536 to - 32768 - 65535/65536.
However precision is a different thing to range. You've got up to 31 bits of precision.
