As stated above - i386 + uClibc 0.9.29 locale works fine when dealing with floats and date output is fine too.
Tested inside the chrooted busybox environment with:

$ /tmp/buildroot/build_i386/staging_dir/usr/bin/i386-linux-uclibc-gcc -static -O0 -ggdb3 test.c -o float.i386
$ cat test.c 
#include <stdio.h>
#include <string.h>

int main (int argc, char *argv[])
{
	double test;
	test = 1.0;
	fprintf(stderr, "Test double = %f.\n", test);
	
	test /= 100;
	fprintf(stderr, "Test double = %f.\n", test);

	test = 10;
	fprintf(stderr, "Test double = %f.\n", test);

	while (test)
	{
		fprintf(stderr, "Test double = %f.\n", test);
		test -= 2;
	}

	return 0;
}
$ sudo chroot ./root /bin/sh
/ $ ./float.i386 
Test double = 1.000000.
Test double = 0.010000.
Test double = 10.000000.
Test double = 10.000000.
Test double = 8.000000.
Test double = 6.000000.
Test double = 4.000000.
Test double = 2.000000.

/ $ set
HISTFILE='/home/hinkok/.ash_history'
HOME='/home/hinkok'
IFS=' 	
'
LOGNAME='root'
PATH='/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/opt/bin'
PPID='25055'
PS1='\w \$ '
PS2='> '
PS4='+ '
PWD='/'
SHELL='/bin/bash'
SUDO_COMMAND='/bin/chroot ./root /bin/sh'
SUDO_GID='1000'
SUDO_UID='1000'
SUDO_USER='hinkok'
TERM='xterm'
USER='root'
_='./float.i386'




Maybe is the pregenerated locale data that is causing problems?? I'll test with own homebuilt locale data instead ..
