how to use ln in Java

Question

I\'m trying to use this formula in JAVA : (-ln(1-L))/L
I\'m not sure how to use ln in java.

Answer 1

Math.log(d) returns the natural logarithm (base e) of a double value.

So the java code will be,

double result = (-Math.log(1-L))/L;

(but note that it's better to have variable names in lower-case - i.e. l instead of L)
