17 // It uses 3 iterations for float32, 4 for float64 and 5 for float128,
19 // every iteration, the two modes are supported: N full-width iterations (as
131   // rep_t-sized iterations may be slower than the corresponding half-width
134   // NB: Using half-width iterations increases computation errors due to
138   // Starting with (n-1) half-width iterations
146   // Use 16-bit initial estimation in case we are using half-width iterations
179   // For half-width iterations, b_hw is used instead of b.
205     // any number of iterations, so just subtract 2 from the reciprocal
219   // For initial half-width iterations, U = 2^-HW
242   // Error estimations for full-precision iterations are calculated just
257   // the total number of iterations should be at least 3 even for float32.
282   // Just like the case of half-width iterations but with possibility
292   // Then like for the half-width iterations:
302   // u_n for different precisions (with N-1 half-width iterations):
331 #error Invalid number of iterations
