Restrictions
| 1. | thinBasic perform all internal numeric calculations using EXTENDED (abbreviated EXT) data type. |
| 2. | due to lack of precision (only 6 digits), we suggest to use SINGLE data type only when interfacing to external libraries that explicitly ask for SINGLE parameters passed by reference. |
