How can I specify the base for Math.log() in JavaScript?

Question

I need a log function for JavaScript, but it needs to be base 10. I can\'t see any listing for this, so I\'m assuming it\'s not possible. Are there any math wiz

Answer 1

Easy, just change the base by dividing by the log(10). There is even a constant to help you

Math.log(num) / Math.LN10;

which is the same as:

Math.log(num) / Math.log(10);
