ieee_retrospective()
The libm function ieee_retrospective() prints to stderr information
about unrequited exceptions and nonstandard IEEE modes. Pascal programs
call
ieee_retrospective() on exit by default.
SPARC Libraries
The libm and libsunmath libraries also contain:
•
Argument reduction functions, using infinitely precise Pi and trigonometric
functions scaled in Pi
•
Data conversion routines for converting floating-point data between IEEE
and non-IEEE formats
•
Random number generators
There are two facilities for generating uniform pseudo-random numbers,
addrans (3M) and lcrans (3M). addrans is an additive random number
generator; lcrans is a linear congruential random number generator. In
addition, shufrans (3M) shuffles a set of pseudo-random numbers to provide
even more randomness for applications that need it.

writeln('IEEE values');

writeln(quiet_nan(l0));
writeln(max_normal);
writeln(max_subnormal);
writeln(min_normal);
writeln(min_subnormal);
end.
