I took this to mean that a tasks entires can be overloaded independently
and not as a group.

NO, the radix of a floating constant is programmer specifiably.
The default for a constant like 1.3E-3 is radix 10, but if you say

        constant                value

        16#E.0#E1               14*(16**1)=224.0
        2#1.1111_1111_111#E11   1.1111_1111_111      *(2**11) = 4095.0
                                               base 2
The radix of the internal representation for FLOAT constants
is implementation defined.
