67b16613ba libs/libc/stdio/lib_dtoa.c: Lots of risky turmoil to get this file closer to the NuttX coding style. Seems to check out, but still risky. libs/libc/stdio/lib_libdtoa.c: A fix for the %g format. The algorithm will sometimes generate number greater than the precision of type double. This adds a check if the precision has been exceeded and logic to remove the least significant garbage. 2019-02-16 18:08:38 -06:00

4dc0636f1e libs/libc/stdio: Add support for %g format which, for these purpose, is equivalent to %f except that trailing zeroes are suppressed. 2019-02-15 11:45:25 -06:00

38e93ede2b Revert "libs/libc/stdio: Fix the %f floating point output format."
The previous implementation was probably corect.  On Cygwin with GCC I see this:

int main(int argc, char **argv)
{
  printf("Value 1.2 is: [%f]\n", 1.2);
  printf("Value 0.1 is: [%f]\n", 0.1);
  printf("Value 0.0: [%f]\n", 0.0);
  printf("Value 347.6872: [%f]\n", 347.6872);
}

Generates output

Value 1.2 is: [1.200000]
Value 0.1 is: [0.100000]
Value 0.0: [0.000000]
Value 347.6872: [347.687200]

This reverts commit eb0223bc7f.

cf99fb40c9 This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now.
Squashed commit of the following:

    libs/libxx:  Fix some confusing in naming.  If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
    libs/:  Fix paths in moved library directories.
    libs:  Brute force move of libc, libnx, and libxx to libs.  Cannot yet build it in that configuration.
