Am I misreading, or are these answers missing the point?
102.0 div 1 ought to yield 102, not 101.

Julifos did not mean to say he wanted to preserve decimals in the final
result. But rather that
set n to 1.015 * 100 --> 101.5
set n to n + 0.5 --> 102.0
(n as small real) div 1 --> 102
gets the right answer. (102)
So does:
set n to 1.015 * 100 --> 101.5
set n to n + 0.5 --> 102.0
n as integer --> 102
Since that's what he's apparently looking for, better to use this coercion.
