The JavaScript Math.log() returns the natural logarithm (base E) of a number.
Syntax:
Math.log(number)
Note: A Number, represents the natural logarithm of a defined number. If the number is negative, NaN is returned.
If the number is 0, -Infinity is returned.
Example:
<!DOCTYPE html>
<html>
<body>
<button onclick="logFunction()">Try it</button>
<p id="example"></p>
<script>
function logFunction() {
var a = Math.log2(2);
var b = Math.log2(1);
var c = Math.log2(0);
var d = Math.log2(-1);
var x = a + "<br>" + b + "<br>" + c + "<br>" + d;
document.getElementById("example").innerHTML = x;
}
</script>
</body>
</html>
Output:
