31 | N = 64(M + M') + j, j = 0,1,2,...,63.
34 | 2**X = 2**(M') * 2**(M) * 2**(j/64) * exp(r).
42 | 3. Set y := X*log_2(10)*64 (base 2 log of 10). Set
44 | N = 64(M + M') + j, j = 0,1,2,...,63.

50 | 10**X = 2**(M') * 2**(M) * 2**(j/64) * exp(r).
54 | 1. Fetch 2**(j/64) from table as Fact1 and Fact2.
57 | Fact1 := 2**(M) * Fact1
58 | Fact2 := 2**(M) * Fact2
59 | Thus Fact1 + Fact2 = 2**(M) * 2**(j/64).
64 | 4. Let AdjFact := 2**(M'). Return
