How to convert a String to long in javascript? -

-

I have a millisecond timestamp that I need to change from string to long. I have a parseInt in javascript but there is no parseLong . So how can I do this?

Thanks

EDIT: To make a little detail on my question: apparently, there is not a long type in JavaScript, I have long been easy How can I make arithmetic, which are initially expressed as strings? To get Delta one time, one has to subtract one from the other?

A number type in javascript which is a 64 bit floating point number * .

If you want to convert a string to a number,

  1. use either if I am using parseInt , So I always want to go through Radix.
  2. Use the Unary + operator e.g. + "123456"
  3. Use constructor example var n = number ("12343")

    * There are circumstances where the numbers will be internally organized as integers.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
