Data types

  Internally FastScript operates with the Variant type and is based on it. Nevertheless, you can use the following predetermined types in your scripts:

Byte      | Same as Integer type

Word      |

Integer   |

Longint   |

Cardinal  |

TColor    |

Boolean   | Boolean type

Real      | Same as Extended type

Single    |

Double    |

Extended  |

TDate     |

TTime     |

TDateTime |

Char      | Char type

String    | String type

Variant   | Same as Variant type

Pointer   |

Array     | Array type

   C++Script maps some types to standard types:

int, long = Integer

void = Integer

bool = Boolean

float = Extended

 JScript has no types, all types are variants. BasicScript may have types (for example, dim i as Integer), or may have no types and even no variable declaration. In this case a variable will have Variant type.

  Not all of these types can be assign-compatible. Like in Object Pascal, you can't assign Extended or String to an Integer. Only one type - the Variant - can be assigned to all the types and can get value from any type.

  Except the built-in types you can use the enumerated types defined in your application or in add-in modules (for example after adding the TfsGraphicsRTTI component you can use TPenMode, TFontStyles and other types).
