the data general and ibm formats and interpretation are IDENTICAL.

there is one difference.  on the data general machine this is an optional
floating point round mode, UNBIASED ROUNDING with two guard digits (hex)
and a sticky bit.  this is equivalent to the ieee rounding mode extended to
hex exponent machines.  thus on the dg machine, using the unbiased round
mode, more accurate answers will be obtained as contrasted to the equivalent
program executed on a ibm machine.
