B&R ECCP70-01浮點支持162Bug支持MC68040微處理器芯片的浮點單元（FPU）。對于MVME162Bug，已擴展命令MD、MM、RM和RS，以允許在寄存器和內(nèi)存中顯示和修改浮點數(shù)據(jù)。浮點指令可以使用MD和MM命令的DI選項進行組合/分解。修改浮點數(shù)據(jù)寄存器或浮點內(nèi)存位置時可以使用的有效數(shù)據(jù)類型：以單精度、雙精度、擴展精度或壓縮十進制格式輸入數(shù)據(jù)時，必須遵守以下規(guī)則：B&R ECCP70-011。符號字段是第一個字段，是一個二進制字段。2.指數(shù)字段是第二個字段，并且是十六進制字段。3.尾數(shù)字段是最后一個字段，是十六進制字段。4.符號字段、指數(shù)字段和尾數(shù)字段的至少第一個數(shù)字必須存在（尾數(shù)字段中的任何未指定數(shù)字都設(shè)置為零）。5.每個字段必須用下劃線與相鄰字段隔開。6.符號和指數(shù)字段中的所有數(shù)字位置必須存在。B&R ECCP70-01
Floating Point Support The floating point unit (FPU) of the MC68040 microprocessor chip is supported in 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 B&R ECCP70-01or 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.B&R ECCP70-01
