[Octave-bug-tracker] [bug #56414] sin function incorrect results when not slicing input

[Doug Stewart]

Follow-up Comment #1, bug #56414 (project octave):

sin(o)=0
sin(pi)=0
sin(2*pi)=0
sin(30*pi)=0
So all your answers should be 0
What you are seeing is rounding errors because of binary representations.
Also when you do -30:-20 it is not stored as [-30 -29 -28 ...-20]
but is expanded when used. So you can see slightly different rounding errors
from the 2 methods.
