A value of class Integer is a positive or negative number without a
fractional part.

LITERAL EXPRESSIONS

PROPERTY

Class

The class identifier for the object. This property is read-only, and its value is always integer.

ELEMENTS

None

OPERATORS

The Div operator always returns an integer as its result. The +, -, *, Mod, and ^ operators return integers or real numbers.

The operators that can have integers as operands are +, -, *, � (or /), Div, Mod, ^, =, �, >, �, <, and �.

COERCIONS SUPPORTED

AppleScript supports coercion of an Integer value to a single-item list, a real number, or a string.

You can also coerce an integer using the synonym Number, but the class of the resulting value remains unchanged:

set x to 7 as number
class of x --result: integer

NOTES

The largest value that can be expressed as an integer in AppleScript is �536870909, which is equal to �(229- 3). Larger integers (positive or negative) are converted to real numbers (expressed in exponential notation) when
scripts are compiled.
