You‘re right; NaN (NaNs and NaNq) is not implemented in RISC5.
Converting correctly strings to/from floating is surprisingly an extremely difficult task.

One quick remark:
It is true that FLOOR cannot handle values >MAX (2^31-1=2147483647) as those values cannot be stored in an RISC-5 INTEGER.
Remember that on RISC-5 i = FLOOR(FLT(i)) is not guaranteed to be true for INTEGERs i > 16777216
