To get base 10 logarithms of E, use the Math LOG10E property. It returns base 10 logarithm of E which is approximately 0.434.ExampleYou can try to run the following code to get base 10 logarithms of E in JavaScript −           JavaScript Math LOG10E Property                        var property_value = Math.LOG10E          document.write("Property Value: " + property_value);          

To get base 2 logarithms of E, use the Math LOG2E property. It returns base 2 logarithm of E which is approximately 1.442.ExampleYou can try to run the following code to get base 2 logarithms of E in JavaScript:           JavaScript Math LOG2E Property                        var property_value = Math.LOG2E          document.write("Property Value is : " + property_value);          

To get the Natural logarithm of 10, use the Math.LN10 property in JavaScript. It returns the natural logarithm of 10, which is approximately 2.302.You can try to run the following code to get Natural logarithm of 10:Example Live Demo           JavaScript Math LN10 Property                        var property_value = Math.LN10;          document.write("Property Value: " + property_value);          

To get the Natural logarithm of 2, use the Math.LN2 property in JavaScript. It returns the natural logarithm of 2, which is approximately 0.693.ExampleYou can try to run the following code to get Natural logarithm of 2 −Live Demo           JavaScript Math LN2 Property                        var property_value = Math.LN2          document.write("Property Value is : " + property_value);           OutputProperty Value is : 0.6931471805599453

To get Euler’s constant value in JavaScript, use the Math E property.

You can use PHP array in JavaScript. It works for a single as well as the multidimensional array. Use the json_encode() method to achieve this.The following is the Multi-dimensional PHP array.$myArr= array( array('Amit', 'amit@example.com'), array('Rahul, 'rahul@example.com'), );Converting PHP multidimensional array into JavaScript. var arr = ; Now, let’s finally learn how to access it to output the email.document.write(arr[1][1]);

In this tutorial, we will learn to convert JavaScript seconds to minutes and seconds. The problem is that we have given the total number of seconds, and we need to represent it in the minutes and second format. We can perform some basic Mathematics operations and solve our problems. Here, we have two different ways to convert the seconds to minutes and seconds. Using the Math.floor() Method In this approach, we will use the Math.floor() method. We will divide the total number of seconds by 60 to convert it into the minutes and apply the Math.floor() method to round down ... Read More

In this tutorial, we will look at how to get the first and last date of the current month using JavaScript. In our daily lives, we frequently deal with dates, and we typically are aware of the day—or, at the very least, the month—we are in. To assist users in determining when something has occurred or will occur concerning their current situation, we display the name of a day or a month. This serves as a wonderful chronology. Following are the approaches to get the first and last date of the month using JavaScript − Using a Date Object ... Read More
