S'Digits denotes the requested decimal precision for the subtype S. The
value of this attribute is of the type
universal_integer. The
requested decimal precision of the base subtype of a floating point type
T is defined to be the largest value of
d for which
ceiling(
d * log(10) / log(T'Machine_Radix)) +
g 1
<= T'Model_Mantissa
where g is 0 if Machine_Radix is a positive power of 10 and 1 otherwise.

The predefined operations
of a floating point type include the assignment operation, qualification,
the membership tests, and explicit conversion to and from other numeric
types. They also include the relational operators and the following predefined
arithmetic operators: the binary and unary adding operators – and
+, certain multiplying operators, the unary operator
abs, and
the exponentiation operator.
40 As for all types, objects of a floating
point type have Size and Address attributes (see
13.3).
Other attributes of floating point types are defined in
A.5.3.
