Using log base 10 in a formula in Java

Question

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?

Answer 1

Math.log10(x)

suffices for floating-point numbers.

If you need integer log base 10, and you can use third-party libraries, Guava provides IntMath.log10(int, RoundingMode). (Disclosure: I contribute to Guava.)
