Parameters or Arguments
number The variety to use in the calculation. It have to be a value that is greater than 0
The log2() function returns the base-2 logarithm of a number.
If the number is 0, the log2() feature will return -Infinity.
If the number is a negative value, the log2() function will return NaN.
Math is a placeholder object that incorporates mathematical functions and constants of which log2() is one of these functions.
console.log(Math.log2(1)); console.log(Math.log2(2.5)); console.log(Math.log2(0)); console.log(Math.log2(-4));
In this example, we have invoked the log2() characteristic the usage of the Math class.
We have written the output of the log2() feature to the net browser console log, for demonstration purposes, to show what the log2() characteristic returns.
The following will be output to the web browser console log:
0 1.3219280948873624 -Infinity NaN
In this example, the first output to the console log back zero which is the base-2 logarithm of 1.
The 2d output to the console log again 1.3219280948873624 which is the base-2 logarithm of 2.5.
The second output to the console log back -Infinity in view that the quantity furnished was once zero
The second output to the console log back NaN due to the fact the variety supplied was once a negative value.
