Corresponding source code
Yes, it is possible to close this patch.
It was submitted into Avr-libc CVS at Jan.2007. The dtostre() function is't a part of libm library, it is't use any math/float operation. It is allocated in stdlib and is a part of libc. Speed is up and accuracy is improved. The bug #11820 (wrong output with precision=3) is excluded. The internal conversion function is used also in dtostrf() and printf() functions (CVS main branch).
