	String to number conversion. How? Jul 30, 2002, 05:49	1
	I want to convert a string to a number in JavaScript... How can I do that? For example: a page that puts a and b together and has window.prompt to define a and b. But when a user sets a to lets say 3 (a = window.prompt("a=?", "3"), this is not a number 3 but a string "3" and therefore cannot be used in calculations. So how can I convert this "3" string (or any other "number" string to a number?)

	Use the parseInt function: Code: number = parseInt("3");

	Right on skunk, or if you have a decimal (floating point) you need this: Code: var decimalStr = "3.2";decimal = parseFloat(decimalStr); Conversely, to switch number variable to string, just concatentate an empty string Code: var int = 3;var intStr = int + "";

	You can also eval - if the circumstances are right - to go both ways. Flawless
