Math.log() method is used to return the natural logarithm base E of a number. If the value of the number is negative, the return value is always NaN. If the value of the number is 0 it will return Infinity.
Syntax:
Math.log(x)
Example:
<script>
var one = Math.log(5);
document.writeln('Output of 5 is : ' + one + '</br></br>');
var two = Math.log(0);
document.writeln('Output of 0 is : ' + two + '</br></br>');
var three = Math.log(-1);
document.writeln('Output of -1 is : ' + three + '</br></br>');
var four = Math.log(88);
document.writeln('Output of 88 is : ' + four + '</br></br>');
</script>Output:
Output of 5 is : 1.6094379124341003 Output of 0 is : -Infinity Output of -1 is : NaN Output of 88 is : 4.477336814478207
