Introduction to BASIC Logarithmic Functions
Logarithmic Functions
BASIC has the logarithmic function of base 10 LOG10(x)，The logarithmic function of base 2 LOG2(x)，and the natural logarithmic function LOG(x) of base e =2.71828....
Any logarithmic function of another base can be defined as follows
Example.

    10 DEF log3(x)=LOG(x)/LOG(3)
    20 PRINT log3(8)
    30 END

[Note]
The natural exponential function is EXP(x).
