octal: 0o17
hexa: 0x100

--Derivative
It is possible to compute the first derivative of a function with one argument using the prime notation: log'(5).
The prime mark (quote) must appear immediately after the name of the function and must be followed by open-parentheses.
The derivative may be plotted e.g. sqrt'(x).
To compute the derivative of an expression you must define the expression as a named function.
Eg f (x) = x ^ 2 + x after insertion type f '(x) to display the graph of the derivative.

--Multi plot

To plot multiple functions on the same 2d graph simply enter them on the same line separated by ";".
