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.
Try that out.
Good luck.
