// ALGORITHM DESCRIPTION
// ---------------------
//
//
//1. The method is based on the relationship of atan2(Y,X) to atan(|Y/X|)
// as follows.
// / sign(Y) atan(|Y/X|) if X > 0
// atan2(Y,X) =
// \ sign(Y)*pi - sign(Y)*atan(|Y/X|) if X < 0
//
// Thus, atan2(Y,X) is of the form atan2(Y,X) = PI + sgn*atan(|Y/X|)
// where PI and sgn can be determined by the four possible combinations of
// of the pair (sign(X),sign(Y)). We concentrate on the numerical method
// for atan(|Y/X|).
//
//2. For |Y/X| < 2^(-64), atan(|Y/X|) ~=~ |Y/X|. Hence, atan2(Y,X) is Y/X
// if X > 0, and sign(Y)*pi otherwise.
//3. For |Y/X| >= 2^(65), atan(|Y/X|) ~=~ pi/2. Hence atan2(Y,X) is sign(Y)pi/2.
//4. For 2^(-64) <= |Y/X| < 2^(-5), atan(|Y/X|) is approximated by a polynomial
// of the form Z + Z*E*polynomial(E), where Z = |Y/X| and E = Z*Z.
//5. For |Y/X| > 2^(5), atan(|Y/X|) = pi/2 + atan(-|X/Y|), and atan(-|X/Y|) is
// calculated using the polynomial in 4 above.
//6. For 2^(-5) <= |Y/X| <= 2^(5), we employ a table lookup method. First,
// we obtain B = 2^k * 1.b1 b2 b3 b4 = 2^k * (1+k/16) that approximate
// |Y/X| to approximately 5 significant bits. Hence, atan(|Y/X|) is
//
// atan(|Y/X|) = atan(B) + atan(Z), where Z = (|Y|-B|X|)/(|X|+B|Y|).
// ~=~ tau + Z + Z*E*polynomial(E), where E = Z*Z.
//
// B has the range from 2^(-6)*(1+14/16) to 2^5 = 2^(5)*(1+0/16), totally
// 163 possible values. These values are calculated beforehand and stored
// in a table. The polynomial is the one used in 4.
//
// Special cases:
// atan2(+-0, +0) = +-0
// atan2(+-0, -0) = +-pi
// atan2(+-0, x) = +-0, for x > 0, and +-pi, for x < 0
// atan2(y, +-0) = +pi/2 for y > 0, and -pi/2 for y < 0
// atan2(+-y, +INF) = +-0, for finite y > 0
// atan2(+-y, -INF) = +-pi, for finite y > 0
// atan2(+-INF, x) = +-pi/2, for finite x
// atan2(+-INF, +INF) = +-pi/4
// atan2(+-INF, -INF) = +-3*pi/4
