THE HYPERCARD CENTER

 HyperTalk Reference

multiply

`multiply `[`chunk`` of`]``` container ¬ by number ```where `container` or `chunk` must contain a number. (You can use the` is a `operator to see if the container is a number.)

The` multiply `command multiplies the number in the container or chunk by `number` and puts the result into the container or chunk. The result is calculated to a precision of up to 19 decimal places.

The result is displayed in a field or the Message box according to the global property` numberFormat.`

Placeholders

container
HyperTalk DefinitionA place where you can store and retrieve a value.

There are six types of containers in HyperCard: a variable, a button, a field, the selection, the Message box, and menus.

```myVariable [the] selection the Message box btn 3 bg btn "Names" card field 1 bkgnd field "Total" menu 2 menu "Edit" ``` Additionally, you can refer to a button or field by its part number:

```card part 1 last background part ``` AppleScript DefinitionAn object that contains one or more other objects, known as elements of the container. In a reference, the container specifies where to find an object. You specify containers with the reserved words `of` or `in`.

You can also use the possesive form (`'s`) to specify containers. For example, in

```first window's name ```the container is `first window`. The object it contains is a name property.

number
An expression that evaluates to a number.

For example:

```169 / 19 pi (60.625 * 500) average(1,4,5,10) i+1 -- (where i is a number) line 1 of fld "Debits"```

Note: Formally, HyperCard distinguishes between factors (simple values) and expressions. The difference between factors and expression matters only if you like to drop parentheses. Most functions take factors as their parameters, which is why` abs of -10 + 2 `returns` 12 `and `abs of (-10 + 2) `returns` 8`. In short, always use parentheses to group things the way you want them to evaluate, and you won’t have to worry about the difference between factors and expressions.
