octave:1> (intmin('int64') - 1)
ans = 9223372036854775807
octave:2> (intmin('int64') - 2)
ans = 9223372036854775807
octave:3> (intmin('int64') - 3)
ans = 9223372036854775807
octave:4> intmin ('int64') - int64 (1)
ans = 9223372036854775807
octave:5> intmin ('int64') - int64 (2)
ans = 9223372036854775807
octave:6> intmin ('int64') - int64 (3)
ans = 9223372036854775807
