Floating Point Support

The floating point unit (FPU) of the MC68040 microprocessor chip is
supported in the 162Bug. For MVME162Bug, the commands MD, MM,
RM, and RS have been extended to allow display and modification of
floating point data in registers and in memory. Floating point instructions
can be assembled/disassembled with the DI option of the MD and MM
commands.

Valid data types that can be used when modifying a floating point data
register or a floating point memory location:

When entering data in single, double, extended precision, or packed
decimal format, the following rules must be observed:

1. The sign field is the first field and is a binary field.

2. The exponent field is the second field and is a hexadecimal field.

3. The mantissa field is the last field and is a hexadecimal field.

4. The sign field, the exponent field, and at least the first digit of the

mantissa field must be present (any unspecified digits in the
mantissa field are set to zero).

5. Each field must be separated from adjacent fields by an underscore.

6. All the digit positions in the sign and exponent fields must be

present.
