+ * ALGORITHM DESCRIPTION:
+ *
+ * HIGH LEVEL OVERVIEW
+ *
+ * Calculate z = (x*x+y*y)
+ * Calculate reciplicle sqrt (z)
+ * Calculate error = z*(rsqrt(z)*rsqrt(z)) - 1
+ * Calculate fixing part p with polynom
+ * Fix answer with sqrt(z) = z * rsqrt(z) + error * p * z
+ *
+ * ALGORITHM DETAILS
+ *
+ * Multiprecision branch for _HA_ only
+ * Remove sigm from both arguments
+ * Find maximum (_x) and minimum (_y) (by abs value) between arguments
+ * Split _x int _a and _b for multiprecision
+ * If _x >> _y we will we will not split _y for multiprecision
+ * all _y will be put into lower part (_d) and higher part (_c = 0)
+ * Fixing _hilo_mask for the case _x >> _y
+ * Split _y into _c and _d for multiprecision with fixed mask
+ *
+ * compute Hi and Lo parts of _z = _x*_x + _y*_y
+ *
+ * _zHi = _a*_a + _c*_c
+ * _zLo = (_x + _a)*_b + _d*_y + _d*_c
+ * _z = _zHi + _zLo
+ *
+ * No multiprecision branch for _LA_ and _EP_
+ * _z = _VARG1 * _VARG1 + _VARG2 * _VARG2
+ *
+ * Check _z exponent to be withing borders [3BC ; 441] else goto Callout
+ *
+ * _s ~ 1.0/sqrt(_z)
+ * _s2 ~ 1.0/(sqrt(_z)*sqrt(_z)) ~ 1.0/_z = (1.0/_z + O)
+ * _e[rror] = (1.0/_z + O) * _z - 1.0
+ * calculate fixing part _p
+ * _p = (((_POLY_C5*_e + _POLY_C4)*_e +_POLY_C3)*_e +_POLY_C2)*_e + _POLY_C1

+ * ALGORITHM DESCRIPTION:
+ *
+ * HIGH LEVEL OVERVIEW
+ *
+ * Calculate z = (x*x+y*y)
+ * Calculate reciplicle sqrt (z)
+ * Calculate make two NR iterations
+ *
+ * ALGORITHM DETAILS
+ *
+ * Multiprecision branch for _HA_ only
+ * Remove sigm from both arguments
+ * Find maximum (_x) and minimum (_y) (by abs value) between arguments
+ * Split _x int _a and _b for multiprecision
+ * If _x >> _y we will we will not split _y for multiprecision
+ * all _y will be put into lower part (_d) and higher part (_c = 0)
+ * Fixing _hilo_mask for the case _x >> _y
+ * Split _y into _c and _d for multiprecision with fixed mask
+ *
+ * compute Hi and Lo parts of _z = _x*_x + _y*_y
+ *
+ * _zHi = _a*_a + _c*_c
+ * _zLo = (_x + _a)*_b + _d*_y + _d*_c
+ * _z = _zHi + _zLo
+ *
+ * No multiprecision branch for _LA_ and _EP_
+ * _z = _VARG1 * _VARG1 + _VARG2 * _VARG2
+ *
+ * Check _z exponent to be withing borders [1E3 ; 60A] else goto Callout
+ *
+ * Compute resciplicle sqrt s0 ~ 1.0/sqrt(_z),
+ * that multiplied by _z, is final result for _EP_ version.
+ *
+ * First iteration (or zero iteration):
+ * s = z * s0
+ * h = .5 * s0
+ * d = s * h - .5
+ *
+ * Second iteration:
+ * h = d * h + h
+ * s = s * d + s
+ * d = s * s - z (in multiprecision for _HA_)
+ *
+ * result = s - h * d
+ *
+ * EP version of the function can be implemented as y[i]=sqrt(a[i]^2+b[i]^2)
+ * with all intermediate operations done in target precision for i=1,..,n.
+ * It can return result y[i]=0 in case a[i]^2 and b[i]^2 underflow in target
+ * precision (for some i). It can return result y[i]=NAN in case
+ * a[i]^2+b[i]^2 overflow in target precision, for some i. It can return
+ * result y[i]=NAN in case a[i] or b[i] is infinite, for some i.

+ * ALGORITHM DESCRIPTION:
+ *
+ * HIGH LEVEL OVERVIEW
+ *
+ * Calculate z = (x*x+y*y)
+ * Calculate reciplicle sqrt (z)
+ * Calculate make two NR iterations
+ *
+ * ALGORITHM DETAILS
+ *
+ * Multiprecision branch for _HA_ only
+ * Remove sigm from both arguments
+ * Find maximum (_x) and minimum (_y) (by abs value) between arguments
+ * Split _x int _a and _b for multiprecision
+ * If _x >> _y we will we will not split _y for multiprecision
+ * all _y will be put into lower part (_d) and higher part (_c = 0)
+ * Fixing _hilo_mask for the case _x >> _y
+ * Split _y into _c and _d for multiprecision with fixed mask
+ *
+ * compute Hi and Lo parts of _z = _x*_x + _y*_y
+ *
+ * _zHi = _a*_a + _c*_c
+ * _zLo = (_x + _a)*_b + _d*_y + _d*_c
+ * _z = _zHi + _zLo
+ *
+ * No multiprecision branch for _LA_ and _EP_
+ * _z = _VARG1 * _VARG1 + _VARG2 * _VARG2
+ *
+ * Check _z exponent to be withing borders [1E3 ; 60A] else goto Callout
+ *
+ * Compute resciplicle sqrt s0 ~ 1.0/sqrt(_z),
+ * that multiplied by _z, is final result for _EP_ version.
+ *
+ * First iteration (or zero iteration):
+ * s = z * s0
+ * h = .5 * s0
+ * d = s * h - .5
+ *
+ * Second iteration:
+ * h = d * h + h
+ * s = s * d + s
+ * d = s * s - z (in multiprecision for _HA_)
+ *
+ * result = s - h * d
+ *
+ * EP version of the function can be implemented as y[i]=sqrt(a[i]^2+b[i]^2)
+ * with all intermediate operations done in target precision for i=1,..,n.
+ * It can return result y[i]=0 in case a[i]^2 and b[i]^2 underflow in target
+ * precision (for some i). It can return result y[i]=NAN in case
+ * a[i]^2+b[i]^2 overflow in target precision, for some i. It can return
+ * result y[i]=NAN in case a[i] or b[i] is infinite, for some i.
