log(var x): var
Logarithm of x with base e.
Parameters:
x
- any var.
Returns:
ln(x)
Remarks:
- For the logarithm with base n, divide by log(n).
For instance, log10(x)
= log(x)/log(10).
Examples:
x = log(1); // x == 0
x = log(2.718); // x == 1 (2.718 is an approximation to the constant e).
x = log(y)/log(2); // x == log2(y), i.e. log(y) base 2.
