Logarithm and Exponential

ln(x)
This function calculates the natural logarithm of x,
e.g. ln(123)=4.812...
log(x; base)
This function calculates the logarithm of x with a base equal 'base'
It's using the formula: log(x; base) = ln(x) / ln(base)
log(123; 4)=3.471...
exp(x)
This function calculates the exponential function of x
exp(20)=e^20=485165195.409...
