It should go without saying that the text char array you suggest must already
exist, and be at least one char longer than the longest string you expect (I'd
make it twice as long).
And use snprintf(3) instead. Bad People (or you) will try to overrun the buffer
if you don't prevent it. (Not
You might want to look at sprintf http://linux.die.net/man/3/sprintf.
sprintf(text, %f, fv) should work just fine.

Yes! I

Knowing which API you mean,
Thanks!
sprintf worked great - Didn't realize that those wonderful Standard C functions
were available.
Again, Thanks

You need to do a string conversion, just like you would in any situation where
you need a textual version of a number.
One possible way:
NSString* s = [NSString stringWithFormat: @%.1f, fv];
const char* sp = s.UTF8String;
another:
char* s[16];
snprintf(s, 16,
