Numeral System mode does not offer fractional conversions. (At least, I can't see any!) Example: I can convert 17D into 10001B. But I cannot convert 17.625D into binary; though this is as straightforward, and results in 10001.101B. Of course, the algorithm needs being implemented, and the comma / dot must not be grayed out. Reproducible: Always
