Sometimes a variable, after lots of calculations, is instantiated to a
float value of -0.0 in the gprolog interpreter. When I compare the
variable to 0.0, as in X =:= 0.0, it succeeds. X < 0.0 fails. What
is the significance of the minus sign? Is the return of -0.0 intentional?
I don't have a simple example as this usually occurs after some
matrix operations with lots of additions and multiplications.
