<p>That's just too expensive to enable by default. For float in general, the number one rule on embedded systems is "don't use at all".</p>

<p>I agree it should not be activated by default. printf_float is not activated by default. But it needs to be documented somewhere (what is the best place for this ?).</p>
<p>We use it on a big STM32 (STM32F446) which have the capacity to use use it. However that cost of nearly 18kB seems unacceptable.</p>
<p>It is more a feature to activate if needed.</p>
