Returns an integer converted from a string.
function parseInt(numString : String [, radix : Number]) : Number
Required. A string to convert into a number.
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.
The parseInt method returns a whole number 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.
You can test for NaN using the isNaN method.
In following example, the parseInt method is used to convert two strings to numbers.
parseInt("abc") // Returns NaN. parseInt("12abc") // Returns 12.
