Take string from UITextField and use it as a double

I'm trying to make a unit converter as my first app. I've been having trouble getting the numeric value from the textfield, so I can multiply it by whatever constant to convert the units. Also, how can I add a decimal place to a numeric key pad?

Use the NSString doubleValue property to convert the string value from the UITextBox into a double.

double d = [str doubleValue];
