How to calculate log base 2 of an Integer in Java?
Given an integer N, the task is to calculate its log to the base 2, i.e. log2 N in Java.
Input: N = 2
loga b = loge b / loge a
- Therefore we can calculate log2 N indirectly as:
log2 N = loge N / loge 2
Below is the implementation of the above approach:
result = (
)(Math.log(N) / Math.log(
+ N +
" to the base 2 = "
Log 1024 to the base 2 = 10
