JSVAL_IS_INT

Obsolete since JSAPI 32
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Determine if a given jsval is a JavaScript number represented in memory as an integer.

Syntax

JSVAL_IS_INT(v)

Description

JSVAL_IS_INT(v) is true if the jsval v is a number represented in memory as an integer.

To test whether a value is a number, regardless of how it is represented in memory, use JSVAL_IS_NUMBER instead.

To convert between C integer types and jsval, use JSVAL_TO_INT, INT_FITS_IN_JSVAL, and INT_TO_JSVAL.

Example

The following code snippet illustrates how a JavaScript variable, MyItem, is conditionally tested in an if statement to see if it is a JS integer data type.

if (JSVAL_IS_INT(MyItem)) {
    . . .
}
