CONFIG_CBPRINTF_FP_A_SUPPORT

Enable floating point %a conversions

Type: bool

Help

The %a hexadecimal format for floating point value conversion was
added in C99, but the output is not easily understood so it rarely
appears in application code.

Selecting this adds support for the conversion, but increases the
overall code size related to FP support.

Direct dependencies

CBPRINTF_FULL_INTEGRAL

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.

Symbols selected by this symbol

CBPRINTF_FP_SUPPORT
