In previous lessons, you learned that the Math.round() method rounds the value to the nearest whole integer.
Here are some examples:
Math.round(6.7); // 7
Math.round(3.2); // 3
This differs from the Math.floor() and Math.ceil() methods, which round down and up to the nearest whole integer, respectively.
Create a new variable called numRounded and assign the result of rounding the number 2.7. Then, log the value of numRounded to the console.
Below that, create another new variable called numRounded2 and assign the result of rounding the number 11.2. Then, log the value of numRounded2 to the console.
You should have a variable called numRounded.
assert.isNotNull(numRounded);
You should assign the result of rounding the number 2.7 to the variable numRounded.
assert.equal(numRounded, 3);
You should not hardcode the value of 3 for the variable numRounded. Make sure you are using the Math.round() method.
assert.notMatch(code, /numRounded\s*=\s*3/);
You should log the value of numRounded to the console.
assert.match(code, /console\.log\(\s*numRounded\s*\)/);
You should have a variable called numRounded2.
assert.isNotNull(numRounded2);
You should assign the result of rounding the number 11.2 to the variable numRounded2.
assert.equal(numRounded2, 11);
You should not hardcode the value of 11 for the variable numRounded2. Make sure you are using the Math.round() method.
assert.notMatch(code, /numRounded2\s*=\s*11/);
You should log the value of numRounded2 to the console.
assert.match(code, /console\.log\(\s*numRounded2\s*\)/);
const botName = "MathBot";
const greeting = `Hi there! My name is ${botName} and I am here to teach you about the Math object!`;
console.log(greeting);
console.log("The Math.random() method returns a pseudo random number greater than or equal to 0 and less than 1.");
const randomNum = Math.random();
console.log(randomNum);
console.log("Now, generate a random number between two values.");
const min = 1;
const max = 100;
const randomNum2 = Math.random() * (max - min) + min;
console.log(randomNum2);
console.log("The Math.floor() method rounds the value down to the nearest whole integer.");
const numRoundedDown = Math.floor(6.7);
console.log(numRoundedDown);
console.log("Now, generate a random integer between two values.");
const randomInt = Math.floor(Math.random() * (max - min) + min);
console.log(randomInt);
console.log("The Math.ceil() method rounds the value up to the nearest whole integer.");
const numRoundedUp = Math.ceil(3.2);
console.log(numRoundedUp);
console.log("The Math.round() method rounds the value to the nearest whole integer.");
