    For x >= 0, signGamma(x) is .plus. For negative x, signGamma(x) is .plus when x is an integer, and otherwise it is .minus whenever trunc(x) is even, and .plus when trunc(x) is odd.

    This function is used together with logGamma, which computes the logarithm of the absolute value of Γ(x), to recover the sign information.
