* grand.c: Updated G_RAND_DOUBLE_TRANSFORM to be more
accurate. Redid g_rand_double() such that it returns 52 bits after
the point instead of 32 as before. That OTOH requires calling
g_rand_int() twice. Overhauled g_rand_int_range(), which is easier
now thanks to the new precision of g_rand_double(). Thanks to
Sverre Johansen <sj@ifi.uio.no> for the hint.
* grand.h: Added g_rand_boolean() and g_random_boolean()
macros. While they could be omitted due to extreme simplicity,
they make intention clearer in code and are therefore good to have.
* grand.c, grand.h: Renamed all 'min' and 'max' parameters to'
begin' and 'end' resp. to avoid making people think, that 'max' is
included in the interval. 'end' now isn't, whereas 'begin'
is. That's similar to the use in the STL.
* glib/glib-sections.txt: Added g_rand_boolean and
g_random_boolean macros.
* glib/tmpl/random_numbers.sgml: Updated.
2000-10-13 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* grand.c: Added inline documentation.
* docs/refernce/glib/glib-sections.txt: Added misc items.
* docs/refernce/glib/tmpl/random_numbers.sgml: Documentation for
the random number generator.

updates the license headers to the GNU Lesser General Public License,
as well as updating the copyright year to 2000.

* grand.c (g_rand_new): Use /dev/urandom, as it doesn't block,
which /dev/random might do. Do not XOR the time, when getting the
seed form /dev/urandom, as this is good itself. Prevent the
initial seed from being zero, which causes the PRNG to produce
only zeros. Hints from Colin Plumb <colin@pgp.com>.
1999-04-12 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h: Moved struct declaration up. Style fixes.
* grand.c: Style fixes. Only try to open /dev/random once.
* tests/rand-test.c (main): New tests; Slight bug fix.
1999-04-09 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* grand.c, tests/rand-test.c: New files to implement the Mersenne
Twister Pseudo Random Number Generator.
* glib.h, AUTHORS, Makefile.am, tests/Makefile.am: Changed
accordingly.
