Microsoft® JScript parseInt Method |
Language Reference Version 1 |
Converts strings into integers.
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.
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.
