No,
This is a platform specific build/optimization issue not a float
precision "bogus bug".
Compile ext/standard/math.c without optimization i.e.
with -O0 instead of -O2, and the bug vanishes:
gcc -I. -I/home/george/php-4.2.1/ext/standard
-I/home/george/php-4.2.1/main -I/home/george/php-4.2.1
-I/home/george/php-4.2.1/Zend
-I/home/george/php-4.2.1/ext/mysql/libmysql
-I/home/george/php-4.2.1/ext/xml/expat -I/home/george/php-4.2.1/TSRM
-g -O0 -c math.c && touch math.lo
(php 4.1.2 i386-pc-linux-gnu Debian Linux test 2.2.18pre21)
I believe BSD always works.
For an even simpler test case, try round(0.35,1);

round(12.555, 2) produces 12.55 not 12.56 as is documented (and as it
should). round(12.556, 2) works fine thou.
