- the original value if the value is finite. This function accepts all
- possible input values.
- INFINITY and -INFINITY are rounded to FLT_MAX and -FLT_MAX.
- NAN values are converted to 0.
- This function will always add a terminating '\0' to the output.
- @param value Any floating-point number
- @param output The buffer to write the string into. Must be non-null.
