<div>> means it can only take an actual hardcoded string.</div>
<div> </div>
<div>if with "hardcoded" you mean a string constant, then the answer is no. "s" is a pointer to any c string, the const part only means that gensym() promises not to modify the string.</div>
<div>google "const correctness".</div>

<div>> Can this convert floats to symbols?</div>
<div> </div>
<div>use a char array together with snprintf, e.g.:</div>
<div> </div>
<div>char buf[100];</div>
<div>snprintf("foo-%f", sizeof(buf), someFloatValue); // NOTE: you should check the return value, if you want to be safe, see https://linux.die.net/man/3/snprintf</div>
<div>gensym(buf);</div>

<div>Thank you.
<div>I have read it.</div>
<div>I understood that the "const" part of "const char *s) means it can only take an actual hardcoded string. Can this convert floats to symbols?</div>
