All numbers in JavaScript are internally represented by 64-bit floating point numbers (see §4.3.19 of the specification). That means it can exactly represent every integer from 0 up to 9007199254740992 (hex value 0x20000000000000). Any integers greater than that (or less than it’s negative counterpart) may need to be rounded to the closest approximate value. Observe: … Read more
This is something I made another time for just numbers, it will allow all the formatters as well. jQuery $(‘input’).keypress(function(e) { var a = []; var k = e.which; for (i = 48; i < 58; i++) a.push(i); if (!(a.indexOf(k)>=0)) e.preventDefault(); }); Try it http://jsfiddle.net/zpg8k/ As a note, you’ll want to filter on submit/server side … Read more
if (floor($number) == $number)
Match against /^\d+$/. $ means “end of line”, so any non-digit characters after the initial run of digits will cause the match to fail. Edit: RobG wisely suggests the more succinct /\D/.test(z).

This can be done quite easily if you: Use str to convert the number into a string so that you can iterate over it. Use a list comprehension to split the string into individual digits. Use int to convert the digits back into integers. Below is a demonstration: >>> n = 43365644 >>> [int(d) for … Read more
I believe it’s true that the input is acceptable if and only if either: It is a prefix substring of the lower bound converted to string or The input followed by any number of additional zeros (possibly none) falls into the range The first rule is required by e.g. 13 is in range (135, 140). … Read more
I’m going to give an example with react usage. It uses state which store the value of the field. But, I think u can replace it with whatever variable you like. <input type=”number” value={Number(this.state.myNumber).toString()}/> In my case, myNumber stores a year number. This way, the year 2018 (for example) won’t be displayed mistakenly as 02018.
HTML5 number input doesn’t have styles attributes like width or size, but you can style it easily with CSS. input[type=”number”] { width:50px; }
Have you tried this Random integer between 0 and 1000(1000 not included): Random random = new Random(); int randomNumber = random.Next(0, 1000); Loop it as many times you want
