CONFIG_CBPRINTF_FP_ALWAYS_A¶

Select %a format for all floating point specifications

Type: bool

Help¶

The %a format for floats requires significantly less code than the
standard decimal representations (%f, %e, %g).  Selecting this
option implicitly uses %a (or %A) for all decimal floating
conversions.  The precision of the original specification is
ignored.

Selecting this decreases code size when FP_SUPPORT is enabled.

Defaults¶

No defaults. Implicitly defaults to n.
