Is there any documentation on what is in NewLibNano?

[wdtj]

We have a project using a LPC54018JxM, MCUXpresso and apparently NewLibNano.  I went to add some floating point code and added a call to gcvt() but apparently that is missing from NewLibNano.  Now I understand that NewLibNano is a stripped down version of NewLib. 

Question I have is, is there any documentation on NewLibNano?  I found some on NewLib and a bunch of "we removed this from Nano" statements in the MCOXpresso user guide.  Is there any documentation on NewLibNano and what it does include?

Thanks for the response.  I was already aware of the newlib docs, but I was more concerned with what was missing or changed from there with newlibnano.  The blueprint link simply indicates that they were going to create that library, but not what was created.

I'm afraid that for details you would have to ask ARM Inc, as the library originates from them (https://blueprints.launchpad.net/gcc-arm-embedded/+spec/newlib-nano), or you would have to check out the sources. https://sourceware.org/newlib/ is a helpful start and you can get files from https://sourceware.org/pub/newlib/

I hope this helps,
