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.
