The above creates a random integer between 0 and 2. The number could be 0,1, or 2. Let's see more finely why this is the case. 1) Math.random() always produces a random number between 0 and 1 2) Math.random()*2 always produces a random number between 0 and 2 3) Math.round(Math.random()*2) always produces a random integer between 0 and 2 The result shows the method that adds the comma to a number by parsing the number string is the most efficient one. Note: Each of the three methods takes a string and assumes the string contains only digits, negative sign, postive sign and period. import java.text.DecimalFormat; import java.util.Random; public class NumberCommafy { private ...
Aug 14, 2014 · Generating a random number with JavaScript is pretty trivially easy: var numRand = Math.floor(Math.random() * 101); That will return a random number between 1-100.
