Application example
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 D3 and D2.
(Example) 0.3452 104 0.0079 104=0.436962 102
0.00

To perform the floating point division, the BCD value
@MOV
in D0 is converted to floating-point format in D101
1
and D100 and the BCD value in D1 is converted to
D100
floating-point format in D103 and D102.

@MOVD
and D100 by the floating-point number in D103 and
D0
D102.
D100
The result of the calculation and the quotient are output
to D3 and D2.
