Nicolas Pitre 90ec5360be prf.c: fix wrong results with %g conversion The precision parameter to the %g conversion indicates the maximum number of significant digits and not the number of digits to appear after the radix character. Here's a few examples this patch fixes: expected before ---------------------------------------------------------- printf("%.3g", 150.12) 150 150.12 printf("%.2g", 150.1) 1.5e+02 150.1 printf("%#.3g", 150.) 150. 150.000 printf("%#.2g", 15e-5) 0.00015 0.00 printf("%#.4g", 1505e-7) 0.0001505 0.0002 printf("%#.4g", 1505e-8) 1.505e-05 1.5050e-05 Signed-off-by: Nicolas Pitre <npitre@baylibre.com>		2019-07-14 23:07:44 -04:00

Title: sprintf() APIs

Description:

This test verifies that sprintf() and its variants operate as expected.

--------------------------------------------------------------------------------

Building and Running Project:

This project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info

--------------------------------------------------------------------------------
