For integers, try
str = parseInt( str, 10 ).(note: the second parameter signifies the radix for parsing; in this case, your number will be parsed as a decimal)
parseFloatcan be used for floating point numbers. Unary+is a third option:str = +str.That being said, however, the term "type" is used quite loosely in JavaScript.
Could you explain why are you concerned with variable’s type at all?
