// PW_STRING_ENABLE_DECIMAL_FLOAT_EXPANSION controls whether floating point
// 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.
