These tests check the RTOI, ITOF, DTOF, FTOD, and FTOI operations.
RTOI: Set operandI to 123.45 and expctcLrslt to 123.0.
Perform RTOI operandI -> MAU FO.
Compare expctcLrslt and MAU FO checking for equality.
ITOF: Set operandI to 123.
Perform ITOR operandI -> MAU FO.
Compare expctcLrslt and MAU FO checking for equality.
FTOI: Set operandI to 123.05 and expctcLrslt to 123.
Clear result.
Move operandI to MA U FO.
Perform FTOI MAU FO -> result.
Compare result and expctcLrslt checking for equality.
DTOF: Set operandI to Ox123a and expctcLrslt to 123.0.
Perform DTOF operandI -> MAU FO.
Compare expctcLrslt and MAU FO checking for equality.
FTOD: Set operandI to 123.00 and expctcLrslt to Ox123a.
Move operandI to MAU FO.
Perform FTOD MAU FO -> result.
Compare result and expctcLrslt checking for equality.
Hardware Tested: The MAU is tested.
Data Returned: The failing test number (last number displayed on the system console prior to
failure) is returned.
Notes: None
