Welcome in the forum!
Easiest solution without any formatting is to use ftoa().
More complex but much more universal is sprintf(). Formatting specifiers here: publications.gbdirect.co.uk/c_book/chapter9/formatted_io.html
Internal enabling see here : www.cypress.com/
So increase stack and address the linker addition.
First, just want say sorry because I created the thread but couldnt type anything on the post due to some weird error on my web browser (Google Chrome).Really appreciate your reply.
Yes I intentionally added another 8K of flash into my code so that it can handle printing or scanning floating point.
The result is same when i adjust the linker files by following your link.
Thank you for your help.
