NiceCalc™ 1.1

NiceCalc 1.1 - powerful scientific calculator for Symbian OS.

Basic Features

• 2 panel skins: dark and bright;
• Minimal positive number: 1E-99;
• Max. positive number: 9.(999)E+99;
• Double-precision (15 decimal places);
• Animation of keystrokes (simplifies navigation);
• 3 modes of angle calculations: degrees, radians, grads;
• Indication of memory cell, current angle unit and function mode;
• Support of "simplified" form for binary operations (see "Usage" section for details);
• Easy and fast "just-one-click" interface. To do an elementary operation, just need one keystroke. To do a scientific operation, need two keystrokes.
  

Usage

Although interface of NiceCalc is quite easy, there is some specific that may be not very clear during the first use. For example, joystick buttons are not used for navigation instead they are used as operation keys. Specific key bindings are:

• Joystick Left button: division operation;
• Joystick Right button: multiplication operation;
• Joystick Up button: addition operation;
• Joystick Down button: subtraction operation;
• Joystick OK button: equal (calculation) operation;
• Pencil button: switch to Function mode (Fn button on NiceCalc panel);
• Call termination button (Red phone key): clear (C button on NiceCalc panel).

Almost all buttons have two assigned labels. To enter the number or operation displayed on some button, just press the button. To enter the operation displayed above some button, switch to the function mode first (press the button Fn), then press the button itself. Function mode is automatically switched off just after the operation is completed. Actually this is some kind of standard behavior of real scientific calculators, so should not confuse.

There are two sorts of operations: unary operations (require 1 argument) and binary operations (require 2 arguments). All binary operations have the same priority, i.e. [2] [+] [3] [*] [4] = 20 and not 24 as it should be according to mathematical rules. This is standard behavior for calculators too, although there are exceptions (standard PC Windows's calculator, for example). Unary operations always have higher priority than binary operations. So [2] [+] [3] [x²] = 11, but [2] [+] [3] [x^y] [2] = 25, because [x²] is unary operation, and [x^y] is binary operation.

NiceCalc supports so-called "simplified" form of binary operations. For example, to calculate 3 • 3 on NiceCalc, it's enough to enter [3] [*] [=]. To repeat the operation (i.e. multiply the result, 9, by 3), just press [=] again etc. This feature is quite helpful and it is regular for majority of real calculators, but not implemented in standard S60 calculator for some unknown reason.
