rtl_printf, just like printk, does not support floating point (this is not
libc...) - you will have to convert it to two integers and print them 
serperately as integers. Something uggly like:

	float x;
	int a1,a2;

	x=23.45;

	a1=(int)x;
	a2=(int)(x-(int)x)*1000;

	rtl_printf("A float in RTLinux: %d.%d\n",a1,a2);
