Python 3 In Python 3, this question doesn’t apply. The plain int type is unbound. However, you might actually be looking for information about the current interpreter’s word size, which will be the same as the machine’s word size in most cases. That information is still available in Python 3 as sys.maxsize, which is the … Read more
In Python 2 (and Python 3) you can do: number = 1 print(“%02d” % (number,)) Basically % is like printf or sprintf (see docs). For Python 3.+, the same behavior can also be achieved with format: number = 1 print(“{:02d}”.format(number)) For Python 3.6+ the same behavior can be achieved with f-strings: number = 1 print(f”{number:02d}”)
It’s 2,147,483,647. Easiest way to memorize it is via a tattoo.
>>> str(42) ’42’ >>> int(’42’) 42 Links to the documentation: int() str() str(x) converts any object x to a string by calling x.__str__().
Try random.randrange: from random import randrange print(randrange(10))
The simplest way would be to use the native Number function: var x = Number(“1000”) If that doesn’t work for you, then there are the parseInt, unary plus, parseFloat with floor, and Math.round methods. parseInt: var x = parseInt(“1000”, 10); // you want to use radix 10 // so you get a decimal number even … Read more
There are some examples on the Mozilla Developer Network page: /** * Returns a random number between min (inclusive) and max (exclusive) */ function getRandomArbitrary(min, max) { return Math.random() * (max – min) + min; } /** * Returns a random integer between min (inclusive) and max (inclusive). * The value is no lower than … Read more
I used the idea from Kerry’s answer, but simplified it since I was just looking for something simple for my specific purpose. Here is what I have: function numberWithCommas(x) { return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, “,”); } function numberWithCommas(x) { return x.toString().replace(/\B(?<!\.\d*)(?=(\d{3})+(?!\d))/g, “,”); } function test(x, expect) { const result = numberWithCommas(x); const pass = result === expect; … Read more
>>> a = “545.2222” >>> float(a) 545.22220000000004 >>> int(float(a)) 545
String myString = “1234”; int foo = Integer.parseInt(myString); If you look at the Java documentation you’ll notice the “catch” is that this function can throw a NumberFormatException, which you can handle: int foo; try { foo = Integer.parseInt(myString); } catch (NumberFormatException e) { foo = 0; } (This treatment defaults a malformed number to 0, … Read more
