To find the log of a number you use one of the logarithmic functions, like so:

octave.exe:1> log10(100) ans = 2 octave.exe:2> log(100) ans = 4.6052

log10() is the base-10 logarithm, and log() is the base-e logarithm. Each logarithmic function is the inverse function of the exponential function in the same base.

octave.exe:3> exp(4.6052) ans = 100.00 octave.exe:4> 10^2 ans = 100
