Probably two integer columns is best, but you could do it with one by
shifting the decimal point right a fixed number of positions on import,
making all values integer.

Many computers cannot represent all possible float values in a floating
point register. While you may not encounter this limitation with the values
used for "Map_Entry_Number" the risk is unnecessary. Converting to integer
values also may provide better performance than using a float.
