| // values passed to the ToString function will be expanded after a decimal |
| // point, or just rounded to the nearest int. Enabling decimal expansion may |
| // significantly increase code size. |
| // |
| // Note: This currently relies on floating point support for `snprintf`, which |
| // might require extra compiler configuration, e.g. `-u_printf_float` for |
| // newlib-nano. |
