CHPRINTF_USE_FLOAT Topic is solved

[steved]

It looks as if the sentiments expressed in this thread have got lost somewhere along the line - CHPRINTF_USE_FLOAT now defaults to TRUE if not specified.

While this is no major issue on the larger devices, on Cortex-M0+ it adds about 5K of code - a big deal when you only have 16K or 32K to start with! (If hard FPU is available, adding float support makes negligible difference - 200 bytes or so)

I suggest the makefile might be the most visible place to include the option - possibly default it to 'TRUE' if the FPU is present and enabled, but certainly FALSE by default in general.

Strange, it must be the unintended effect of some patch, it is FALSE in 16.1.x.

Fixed.

Looks like this has crept back in 17.6.2

Too late for 17.6.2, it will go in the next one.

Fixed as bug #890.
