What happens when I check the "Small C library" option in the System Library properties page in the Nios® II IDE?

Description

When the "Small C library" option is checked, the system library uses a reduced implementation of the Newlib ANSI C standard library. Notably, the printf() family of routines (printf(), fprintf(), sprintf(), etc.) does not support floating-point values when this option is checked. The reduced library is optimized for smaller memory footprint, although the implementation may be less time efficient.
