Converts 10 into a real number format data
and stores the result in D0 and D1.
Executes Loge10 operation and stores the
result in D2 and D3.
Converts 12 into a real number format data
and stores the result into D4 and D5.
Divides D4 and D5 (12) by D0 and D1 (10),
and stores the result (1, 2) in D6 and D7 (1, 2).
Multiplies D2 and D3 (Loge10) by D6 and
D7 (1, 2) and stores the result in D8 and D9.
Executes Loge(D8, D9) operation and stores
