log proc

Format

• log(X,Y)
• log(Y)

Returns

The logarithm (base X) of Y. If X is not specified, a natural logarithm is computed (base 2.718…).

The logarithm is the power to which you have to raise X in order to get Y. In other words, the following is true (ignoring round-off error):

X ** log(X,Y) == Y

One nice property of this function is that it gradually increases, with a slope that continuously tapers off. In other words, it can be useful to represent diminishing returns from some input, such as money, experience points, and so forth.
