the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8. In the same fashion, since 102 = 100, then 2 = log10 100.

In what context?
Sometimes in statistics it's useful. If you graph you data and it looks like a log dependence then you can fit
log y vs x with a linear dependence
then exponentiate to get the function dependence of y vs x.
Is that the context you were thinking of?
Also, if your data is spread over a very large range you might use logs. There exists log-log, semi-log graph paper that we old guys used.
