This is similar to
This line gives the error
float y = atanf(x);
The error is
Invalid arguments 'Candidates are:float atanf(float)'
I tried
1) enable provider "CDT GCC Built-in Compiler Settings [ Shared ]".
2) clean; reindex; build
3) rewrite code as
float tan_arg = x;
float y = atanf(tan_arg);
To keep moving forward, I disabled check arguments on that line, but I'm looking for a better solution.
