This appendix presents the supported vector data types and literals. Note that these types are only recognized when all of the following compiler options are enabled:

The following table lists the supported vector data types and the size and possible values for each type.

Type | Interpretation of content | Range of values |
---|---|---|

vector unsigned char | 16 unsigned char | 0..255 |

vector signed char | 16 signed char | -128..127 |

vector bool char | 16 unsigned char | 0, 255 |

vector unsigned short | 8 unsigned short | 0..65535 |

vector unsigned short int | ||

vector signed short | 8 signed short | -32768..32767 |

vector signed short int | ||

vector bool short | 8 unsigned short | 0, 65535 |

vector bool short int | ||

vector unsigned int | 4 unsigned int | 0..2^{32}-1 |

vector unsigned long | ||

vector unsigned long int | ||

vector signed int | 4 signed int | -2^{31}..2^{31}-1 |

vector signed long | ||

vector signed long int | ||

vector bool int | 4 unsigned int | 0, 2^{32}-1 |

vector bool long | ||

vector bool long int | ||

vector float | 4 float | IEEE-754 values |

vector pixel | 8 unsigned short | 1/5/5/5 pixel |

The compiler considers any long vector data type compatible with the corresponding `int vector` type.

Note:

§ The `long` vector types are deprecated.

The following table shows the supported vector literals and how the compiler interprets them to determine their values.
