<<What about support of the 3 floating point types of the x86
architecture,
 32-bit IEEE (7 digits), 64-bit IEEE (16 digits) and the internal FPU
format
 (19 digits).
 
 Most compilers do *not* support the last.>>

<<I am very surprised if that last statement is true. Most certainly
GNAT
 supports the extended precision type on the x86 (it is called
Long_Long_Float).
 
 Note that any compiler not supporting this type is not a conforming
 implementation. B.2(10) is a normative requirement:
 
    10  Floating point types corresponding to each floating point format
        fully supported by the hardware.>>

Does GNAT support the IEEE representations of infinities and
Not-A-Number (nan) specified in "IEEE Standard for Binary Floating-Point
Arithmetic ANSI/IEEE Std 754-1985" or "IEEE Standard for
Radix-Independent Floating-Point Arithmetic ANSI/IEEE Std 854-1987"?
