| 32 Then, all operators for this machine mode will be created. | |

| 34 Or, we need to define FROM_* TO_* for conversions from one mode to another | |
| 35 mode. The mode could be one of the following: | |

| 37 Accum: HA, UHA, SA, USA, DA, UDA, TA, UTA | |

| 39 Unsigned integer: UQI, UHI, USI, UDI, UTI | |
| 40 Floating-point: SF, DF | |
| 41 Ex: If we define FROM_QQ and TO_SI, the conversion from QQ to SI is | |
