At the core of the PROKON suite lies Calcpad, from where you launch the various analysis and design modules. You can use Calcpad to collect the output from the design modules, build calculation sheets with design notes, drawings and equations. CalcPad is a portable smart notepad that calculates answers based on what is typed in. It allows you to type in math expressions, assign variables, define functions, convert units, add units together and much more.
You will find many examples of how to use CalcPad here.

Intro
![Calcpad Calcpad](https://browserengine.net/wp-content/uploads/DownZemAll-is-an-open-source-download-manager-for-Windows-Linux-and-macOS.jpg)
Here is a quick look at some of the features.
Variables
This is one of the most basic features. Scrivener 2 80 3 download free. So I put some extra time into it.
Reserved Variables
CalcPad stores the value of previous lines in different ways. Keep in mind that any line that uses 'total' or 'sum' is defined as a 'total line' or 'sum line'. So a line that just says 'total' or a line that says 'total + 500' are both considered to be a 'total line'.
Constants
![Calcpad Calcpad](https://tekagen.com/calcpad/docs/ss/Units.png)
Constants are not case-sensitive by default (some are made to be case-sensitive though). Most constants are accessible through the Constants Menu as well. However, many constants have alternative names, these can be found in the Data Menu.
User-Defined Functions
Number Syntax
Convert To Words
Convert to Fractions
Tips & Sales
Vectors
Number Bases
Units
CalcPad uses the values of base units to build other units. There is no 'meter/second²' saved anywhere in CalcPad. It builds these units on the fly by combining base units. This allows CalcPad to supports tons and tons of units.
Currency
List of different currencies can be found here.
Physics
As you can see it's easy to setup a formula in CalcPad and re-use it. You can even add your own permanent functions from the Data menu.
Logic
Bitwise
Summation
Extra Stuff
You can copy/paste the input from the demos in this section into CalcPad to see them work. Moviesherlock 6 0 8 equals.
Variable Inception
If you copy/paste this into CalcPad and change 'a', the changed will propagate all the way down to '2f'.

Metric Prefixes Everywhere
You can add metric prefixes to pretty much anything. CalcPad doesn't store units like kilogram or kilometer, it stores the prefixes themselves and then combined them with units when needed. It will even combine with a literal number.

Large Numbers
Yes, these are real numbers. Although, at this point knowing the names don't help you comprehend them any better.

Bitwise: Odd/Even Check
You can use the bitwise & operator to determine if a number is even or odd. If you & a number by 1 it will return 0 if even and 1 if odd. This works because there is only one odd slot. Try visualizing it: 0, 1, 2, 4, 8, 16, 32, etc. Every slot is even except for '1'. The & operator only returns 1/true if both sides are 1/true. So it only returns 1/true if the number if the 1 bit is set (i.e. is odd).

Bitwise: Swap Two Values With Only Two Variables
Typically, if you want to swap the values of two variables, you need a 3rd variable. But with bitwise you don't need that extra variable. You can try it yourself in CalcPad.

a = 8 b = 3 a = a XOR b b = a XOR b a = a XOR b a b | 8 3 11 8 3 3 8 |
Powerball Meme
During 2015 an image started circulating Facebook, claiming that if everyone split the money from Powerball we'd all get $4.33 million! That doesn't sound right. In CalcPad, instead of counting zeros while typing in 1300000000 / 300000000 you can use commas: 1,300,000,000 / 300,000,000. Or, you can just type in 1.3 billion / 300 million.

---|---|
$1300000000 / $300000000 $1,300,000,000 / $300,000,000 $1.3 billion / $300 million | $4.33 $4.33 $4.33 |

WebAssigncalcPad® questions are displayed with a rectangular answer box similar to answer boxes used for other question types, but when you click a calcPad-enabled answer box, the calcPad palette opens, allowing you to answer the question with a correctly formatted expression.
Calcpad 1 1/5
- Click the answer box to open the tool palette.Note Don't use the keyboard to navigate to the answer box.
- Click the tool palette buttons or type to answer the question.
- Tool palette buttons are organized in expandable groups, such as Operations and Trig.
- Some buttons insert placeholder boxes to show you where you can type numbers, variables, or expressions. For example, if you insert a fraction, placeholder boxes are displayed for both the numerator and denominator.
The expression is displayed in the answer box as you enter it. If necessary, the answer box becomes larger to fit your answer.To do this
Do this Enter variables.Type the variable name using the case and spelling specified in the question. Variables are automatically italicized.Enter symbols like π or ∞.Click Symbols and click the symbol.Move the insertion point in the answer box.Press the HOME, END, and arrow keys.Move the insertion point into or out of a placeholder box.Press the arrow keys or use the mouse.Note Usually the insertion point is automatically moved to a placeholder box when it is created.Delete a character, the selected expression, or notation such as fractions.Press BACKSPACE or DELETE.If you have trouble typing your answer, try using the pad buttons.Note- Answers are case-sensitive; x and X are not the same.
- Do not type commas in numbers; 5,280 is not correct.
- Use the pad button when entering fractions between commas (for example, fractions in a list). This notation can be typed, but not intuitively. See the examples for details.
- Do not enter mixed numbers, for example, 2½. Instead, use decimals or improper fractions.
- When entering scientific notation, always use a lowercase e and an integer exponent, for example, 1.23e-5.
- Unless instructed otherwise, express angles for trigonometric functions in radians.
- Keyboard characters that are not mathematically useful — for example, &, @, and foreign language characters — are intentionally not displayed when typed. To enter Greek characters, use the buttons or keyboard shortcuts for the tool.
- Do not use function notation — for example, f(x) — as these answers can't be graded.
- Do not round your answer unless the questions instructs you to.
