Hello, I am getting the same error, did you figure out why you need to comment out the MACRO ?

Thanks PeterR and chegewara. Your suggestions led me to the gcvt function: https://www.geeksforgeeks.org/gcvt-convert-float-value-string-c/ Hello, do you have an example of how you used gcvt ? I used #include <stdlib,h> but I still get an error : error: 'gcvt' was not declared in this scope Thank you
