Examples
When wrap occurs, -(-1) = -1 :
fipref('NumericTypeDisplay','short', ... 'fimathDisplay','none'); format short g a = fi(-1,true,8,7,'OverflowMode','wrap')
a = -1 numerictype(1,8,7)
-a
ans = -1 numerictype(1,8,7)
b = fi([-1-i -1-i],true,8,7,'OverflowMode','wrap')
b = -1 - 1i -1 - 1i numerictype(1,8,7)
-b
ans = -1 - 1i -1 - 1i numerictype(1,8,7)
b'
ans = -1 - 1i -1 - 1i numerictype(1,8,7)
When saturation occurs, -(-1) = 0.99... :
c = fi(-1,true,8,7,'OverflowMode','saturate')
c = -1 numerictype(1,8,7)
-c
ans = 0.99219 numerictype(1,8,7)
d = fi([-1-i -1-i],true,8,7,'OverflowMode','saturate')
d = -1 - 1i -1 - 1i numerictype(1,8,7)
-d
ans = 0.99219 + 0.99219i 0.99219 + 0.99219i numerictype(1,8,7)
d'
ans = -1 + 0.99219i -1 + 0.99219i numerictype(1,8,7)
