Gregory Nutt	e5ea84c1ff	libs/libc/stdio: A few more coding standard fixes for nano-printf file: all global data names must begin with g_. All structure names must end with _s.	2019-02-06 17:05:01 -06:00
Keith Packard	e05149b745	libs/libc/stdio: Add newlib-nano fprintf as an option. This fprintf code was originally adapted from AVR libc and provides improved floating point output support, including 'g' mode and making 'f' mode include digits past the decimal by default. However, this version does not have any long long support. On a demonstration cortex M4 build, this version saves about 5kB of ROM. The newlib version can be found here: https://salsa.debian.org/electronics-team/toolchains/newlib-nano . That project is GPL overall, but the newlib-nano printf portions are BSD licensed as described in the COPYING.NEWLIB file.	2019-02-06 15:50:52 -06:00
