parseInt Method (Windows Scripting - JScript)

  • Article

 

Returns an integer converted from a string.

Syntax

parseInt(numString, [radix]) 

Arguments

  • 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 hexadecimal 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.
