Microsoft® JScript™ parseInt Method | Language Reference Version 1

See Also Applies To

##### Description

> Converts strings into integers.

##### Syntax

> parseInt(numstring, [radix])

> The parseInt method syntax has these parts:

> Part | Description
> numstring | Required. A string to convert into a number.
> radix | Optional. A value between 2 and 36 indicating the base of the number contained in numstring. If not supplied, strings with a prefix of '0x' are considered hexidecimal and strings with a prefix of '0' are considered octal. All other strings are considered decimal.

##### Remarks

> The parseInt method returns an integer value equal to the number contained in numstring. If no prefix of numstring can be successfully parsed into an integer, NaN (not a number) is returned.

> >     parseInt("abc")    // Returns NaN.
> >     parseInt("12abc")  // Returns 12.

> You can test for NaN using the isNaN method.
