One of the problems people may face in Computer Science, is a CPU only capable of computing a logarithm in one base, say 2, but the need to compute a logarithm in another base, say (e). The way to convert is as follows:
c log2(t) == logb(t)
If (t == b), it follows that:
c log2(b) == logb(b) == 1
Hence,
c = 1 / log2(b)
