| 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. |
