JScript Global Object parseInt Method

Converts strings into integers.

Syntax: JScript Global Object parseInt Method

parseInt(numstring, [radix])

Arguments: JScript Global Object parseInt Method

numstring

A string to convert into a number. Required.

radix

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. Optional.

Remarks: JScript Global Object parseInt Method

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.
