Problems with parseInt() - Alternatives?

Problems with parseInt() - Alternatives?

Problems with parseInt() - Alternatives?

Hey everyone,

Here's the thing...I've used parseInt(data) to be able to do operations with the entries in specific input text boxes...It works great if the user writes the numbers correctly...but if the user enters a number with a zero in front of it (045), that number isn't used correctly...it'll be equal to 37...and 049 is equal 4 (??) I don't understand what's happening...I was wondering if there are other ways to evaluate caracters as numbers?

Hope I'm being clear...if not, let me know!

Thanks :)

RE: Problems with parseInt() - Alternatives?

try: Parseint(your_number, 10)
because if your number begins with a 0, parseInt thinks it's hexadecimal - you have to set the base

RE: Problems with parseInt() - Alternatives?

Thank you, it worked :)

RE: Problems with parseInt() - Alternatives?

Using the variable name data as an example, we could also say:

data = new Number(data)
than use window.isNan(data) to be sure they only typed in numbers, parseInt can give the user the wrong idea cuz it will accept things like 1005snarfoofoo


RE: Problems with parseInt() - Alternatives?

maybe not SNarfOOfOO as s, n and o are not hexadecimal figures - but 1005arff would b accepted, yes ;)

RE: Problems with parseInt() - Alternatives?

small correction:  if the number starts with a 0, parseInt treats it as octal, not hex.
