Welcome to Numipulator, the foremost numerical manipulator and calculator from TopAccolades Ltd.

Numipulator enables you to carry out calculations on individual numbers and on lists of numbers, to determine properties of lists of numbers, including statistical functions, and to manipulate lists of numbers. This feature distinguishes Numipulator from both calculators and spreadsheets, as it has both numbers and lists as core object types. Numipulator also lets you generate and format tables, both in text and graphical form.

In many ways you should find Numipulator easier to use than a calculator or a spreadsheet. Compared to a calculator, it has the advantage that inputs remain visible: no need to double-check that you entered everything correctly. Compared to a spreadsheet, it also has many advantages: no need to enter formulae, just select the operation or function; operations remain visible, unlike the hidden formulae of spreadsheets; and its extensive list manipulation functionality.

Numipulator has very flexible input/output formatting, which means that you can, for example, copy a complete spreadsheet worksheet (assuming it comprises only numbers) and paste it into a small input field in Numipulator, ready for manipulation and calculation, e.g. searching for rows matching certain criteria. The output from Numipulator's table formatter may be copied and pasted back into a spreadsheet. Numipulator and a spreadsheet working together are a powerful combination.

Individual calculations and manipulations are specified in numipulation boxes. These are modelled on the way you probably first learned to carry out addition, subtraction and so on at school. There, you probably laid out a simple calculation something like this:

23
  45 +
---
68

That is, the inputs were placed underneath each other, a line was drawn, and the result was put underneath. The operation to be carried out was also made clear (+, or addition, in this case).

A numipulation box is essentially a computerized version of this. For example, a numipulation box for carrying out simple operations on two numbers, such as addition and subtraction, looks like this:

The main components of this are as follows:

• At the top is a general description of the type of numipulation box - in this case Number Operation.  
• The next two lines (in this case) are input fields, with labels.  
• The next line normally consists of a drop-down list, from which you can select the operation (or function in other cases) to be carried out. The text shown in this may refer to the input labels, as in this case.  This operation field separates the inputs from the result.
• Below this line is a result or output field, which also has a label (A1 in this example).  This label is the reference name of the numipulation box - a key feature
• On the bottom line, with a yellow background, is a note field, in which you can add some text describing the output (or inputs);

Once the inputs have been entered, and the operation selected, the = button (Calculate) may be pressed; the result is shown in the result field (as shown above).

The reference name may be an input to any other numipulation box, enabling you to string together many calculations and manipulations in order to achieve your desired output, including any formatting of the output, all in one calculation, by pressing the = button, for example:.

Numipulator also has a processing engine, which enables you to perform a sequence of calculations using the numipulation boxes, rather than just one. This feature, together with the following features:

• special memory numipulation boxes that take an output from one calculation and use it as input in the next cycle;
• its graphics formatter and its ability to display colours and borders, as well as values, for its cells;
• the graphics formatter's ability to respond to clicks on its cells as inputs to the calculation;
• input and output mapping of numbers to text and symbols, meaning that you may have text in your interface, inputs and outputs;

Numipulator provides many built-in Numiplets, some business-related, some demonstrations, and some games or puzzles. We suggest you try these early on to help you to see and understand the power of Numipulator.

Essentially, then, when you define the inputs and selected function/operation of the numipulation boxes, including linking them up, and specifying constraints on the number of repetitions, you are creating a program. Numipulator can therefore be considered as providing a programming environment: one where you don't write programs that tell the computer how to go about executing the program. Such programming is called declarative programming.
