Is there a function, or what is considered the
best way, to convert a float to a char[]?

any help is appreciated

It's been awhile, but

    float f;
    char sz[101];
    sprintf(sz, "%G", f);

Depends on what you want to do and what your formatting needs happen to be.
sprintf() works fine and its quick and dirty. You can probably do better
by looking around at other library's source code for floating point
conversion (e.g., FreeBSD's sprintf(), glibc's sprintf(), etc.) and writing
your own conversion shim.
