SGN_NORM_METHOD_0 1:0 0x0 There are 3 methods of normalizing signed numbers:
|
|
0: SGN_NORM_ZERO : value / (2^(n-1)-1), so -
|
|
128/127 will be less that -1.0, -127/127 will yeild -1.0,
|
|
0/127 will yield 0, and 127/127 will yield 1.0 for 8-bit
|
|
numbers.
|
|
1: SGN_NORM_ZERO_CLAMP_MINUS_ONE: Same
|
|
as SGN_NORM_ZERO except -128/127 will yield -1.0
|
|
for 8-bit numbers.
|
|
2: SGN_NORM_NO_ZERO: (2 * value + 1)/2^n, so -
|
|
128 will yield -255/255 = -1.0, 127 will yield 255/255 =
|
|
1.0, but 0 will yield 1/255 != 0.
