Obsolete
This feature is obsolete.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.

The Number.toInteger() method used to evaluate the passed value and convert it to an integer, but its implementation has been removed.

If the target value is NaN, null or undefined, 0 is returned. If the target value is false, 0 is returned and if true, 1 is returned.

Syntax

Number.toInteger(number)

Parameters

number
The value to be converted to an integer.

Examples

Using toInteger

Number.toInteger(0.1);     // 0
Number.toInteger(1);       // 1
Number.toInteger(Math.PI); // 3
Number.toInteger(null);    // 0

Specifications

Number.toInteger() was part of the draft ECMAScript 6 specification, but has been removed on August 23, 2013 in Draft Rev 17.
