| Convert a float into a decimal string. | |

| not use scientific notation.) and `sscanf(output, "%f", &x)` will return | |
| 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. | |
