2 - Characteristics

   2.1 - Variables

   You can define and use a memory-limited number of  variables.
   To see the full variables list, choose the Windows->Variables
    menu item.

   2.2 - Constants

   Constants are not user-modifiable, but they can be used in your calculus.
   To see the full  constants list, choose the Windows->Constants
    menu item.

   2.3 - Users functions

   You can define and use a memory-limited number of  functions.
   To see the full  functions list, choose the Windows->User functions
    menu item.

   2.4 - History

   All of your expressions and results are saved in the history.
   The max line number of it can be modified in the  Preferences window
   or with the  tooltypes.

   You can load/save an history by accessing to the History menu item from the  main window menu.

   To copy an expression or a value from the history to the  input zone, simply
   clic on the choosen line and clic on the [EXPR] button of the  Main window,
   or choose the History->Expression menu item. In addition, it's also possible to double-clic on the
   choosen line and the resulting action will be determinated by the default mode of the
    Preferences window.

   2.5 - Builtin scientifics functions

   All classic scientifics functions are available:

    Int : Integer value of a number
    Dec : Decimal value of a number
    Abs : Absolute value
    !  : Fact
    @  : Modulo
    %  : Divide a number by 100
    x²  : x power 2
    x³  : x power 3
    x^y : x power y
    x-¹ : x power -1
    10^x : 10 power x
    EXP : Multiply by 10 power something
    Rac² : Square root
    Rac³ : Cubic root
    Rac n : nth root
    e^x : Exponential
    Ln  : Neperian logarithm
    Log : Decimal logarithm
    Sin : Sine
    Cos : Cosine
    Tan : Tangeant
    Cot : Cotangeant
    ASin : Arc Sine
    ACos : Arc Cosine
    ATan : Arc Tangeant
    SinH : Hyperbolic Sine
    CosH : Hyperbolic Cosine
    TanH : Hyperbolic Tangeant
    ASinH : Hyperbolic Arc Sine
    ACosH : Hyperbolic Arc Cosine
    ATanH : Hyperbolic Arc Tangeant

   To see the full scientifics functions list, choose the Windows->Scientifics functions
    menu item.

   It's possible to copy a scientific function in the  input zone by double-
   clicking on it's line or by simple-clicking on it's line followed by a clic on the
   [OK] button.

   2.6 - Builtin programmers functions

   All functions a programmer need:

    And : Logical AND
    Or  : Logical OR
    XOr : Logical eXclusive OR
    Not : Logical NOT
    <<  : Left rotate
    >>  : Right rotate
    <  : Left shift
    >  : Right shift

   To see the full programmers functions list, choose the Windows->Programmers functions
    menu item.

   It's possible to copy a programmer function in the  input zone by double-
   clicking on it's line or by simple-clicking on it's line followed by a clic on the
   [OK] button.

   N.B.: in scientific's  calc mode, you can convert numbers between
   different calc bases (see  input zone).
