Floating-point Division of Two BCD Numbers
In this example, the 4-digit BCD number in D0 is divided by the 4-digit BCD
number in D1 and the floating-point result is written to D2 and D3.
To perform the floating point division, the BCD value in D0 is converted to
floating-point format in D2001 and D2000 and the BCD value in D1 is con-
verted to floating-point format in D2003 and D2002.
