Listing 7.05 - Using Math.min and Math.max

var showSmaller = function (num1, num2) {
    var smaller = Math.min(num1, num2);
    var larger = Math.max(num1, num2);

    console.log(smaller + " is smaller than " + larger);
};

showSmaller(12, 3);
showSmaller(-10, 3);

Further Adventures

Listing 7.05 - Using Math.min and Math.max - Task 1

Try out some different arguments.

var showSmaller = function (num1, num2) {
    var smaller = Math.min(num1, num2);
    var larger = Math.max(num1, num2);

    console.log(smaller + " is smaller than " + larger);
};

showSmaller(12, 30);      // 12
showSmaller(1.2, 0.12);   // 0.12
showSmaller(0, -4);       // -4
showSmaller(-10, -13);    // -13

Listing 7.05 - Using Math.min and Math.max - Task 2

Write a showLarger function.

var showLarger = function (num1, num2) {
    var smaller = Math.min(num1, num2);
    var larger = Math.max(num1, num2);

    console.log(larger + " is larger than " + smaller);
};

showLarger(12, 30);      // 30
showLarger(1.2, 0.12);   // 1.2
showLarger(0, -4);       // 0
showLarger(-10, -13);    // -10

Listing 7.05 - Using Math.min and Math.max - Task 3

Write a showSmallest function that takes three arguments and displays the smallest of the three.

var showSmallest = function (num1, num2, num3) {
    var smallest = Math.min(num1, Math.min(num2, num3));

    var message = smallest + " is the smallest of ";
    message += num1 + ", " + num2 + " and " + num3;

    console.log(message);
};

showSmallest(12, 3, 15);        // 3
showSmallest(-1.2, 0.12, 12);   // -1.2
