Follow-up Comment #5, bug #50947 (project octave):

Response using myatan2 mex:

MATLAB

>> myatan2 (0, 0)
myatan2 (0, 0) = 0

>> myatan2 (-0, 0)
myatan2 (-0, 0) = -0

>> myatan2 (0, -0)
myatan2 (0, -0) = 3.14159

>> myatan2 (-0, -0)
myatan2 (-0, -0) = -3.14159

>> atan2 (0, 0)
ans =     0

>> atan2 (-0, 0)
ans =     0

>> atan2 (0, -0)
ans =     0

>> atan2 (-0, -0)
ans =     0
