Using log base 10 in a formula in Java

I'm trying to write a Java program that can take values and put them into a formula involving log base 10.

How can I calculate log10 in Java?

Solution

  • It looks like Java actually has a log10 function:

    Math.log10(x)

    Otherwise, just use math:

    Math.log(x) / Math.log(10)
