Nicolas Pitre d28434b4fa prf.c: remove buffer limitation on precision and padding for floats
Even if the code used to limit the precision to the on-stack buffer
size, it was still possible to do:

    printf("%f", 1.0e300);

which would overflow the stack and crash the program. Let fix this issue
and remove the precision limitation by recording the number of zeroes to
insert while converting the value and generating those zeroes only
when outputting the data.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.

Getting Started
***************

Welcome to Zephyr! See the `Introduction to Zephyr`_ for a high-level overview,
and the documentation's `Getting Started Guide`_ to start developing.

Community Support
*****************

Community support is provided via mailing lists and Slack; see the Resources
below for details.
