You can use sprintf. Takes up a bit of memory, but youcan do someyhing like

float value = 1.314;
char buffer[BUFFERSIZE];

sprintf(buffer, "Float = %f", value);

Circuit Cellar magazine #187 (February 2006) contains the article "Output Real Numbers" which I think answers your question. The article contains the source code for a very efficient ftoa function.
