Syntax
set myInt to 12 as integer
Description
An integer
value type is a positive or negative
number that does not have a decimal part. You can use
number
as a synonym for
integer
, but the class of the variable remains
integer
, as in:
set aNum to 30 as number
If you get the class
property of
aNum
, it will be integer
.
If you need a very high number, such as for a variable that will hold
the U.S. national debt, you will have to use a
real
data type. An integer
has
a range of-536870911 to +536870911. If you’re going
to work with very high numbers, particularly if the script will
increase the value of those numbers, then you should use a
real
value type to hold the value.
Examples
Here are some examples of numbers that AppleScript will store as integers, as well as numbers that AppleScript will end up storing as reals because they are too big or have a fractional part:
integer class
set bigInt to 500000000
integer class
set bigInt to -500000000
The variable bigInt
is stored in a
real
data type because of the size of the number:
set bigInt to 600000000
The variable bigInt
is converted to the
real
class because it has a fractional part:
set bigInt to 6.1
AppleScript automatically sets a data type for a variable depending
on the size of the number or whether it has a decimal point. In the
following code, the number starts out as an
integer
, has a number with a decimal point added
to it, then is converted to a real
value type to accommodate ...
