Basic math

< return to help

The main window for Andalib Calculator has two boxes, the bottom box is the input box and the top box is the history

1. Click on the input box
2. Type 1+1
3. Press Enter

Conversions

To do a conversion type in the value you want to convert then use the conversion menu to select the unit to go from, then the unit to go to.

1. Click on the input box
2. Type in 100
3. Click on the conversion menu, then temperature, celsius, fahrenheit
4. Input box will now contain 100[c->f]
5. Press Enter

Advanced math

Powers are written using the carrot symbol, ^. E.g. 2 to the power of 3 is written as 2^3. [Note: to write negative powers, write the power in paranthesis like this 2^(-1)].

Factorials are written using the exclamation mark, !. E.g. 4 factorial, or 4*3*2*1, is written as 4!.

In addition to these operators the application also supports the following math functions:

• cos - cosine
• sin - sine
• tan - tangent
• log - natural logarithm
• exp - exponential
• sqrt - square root
• mod - modulus aka remainder i.e. 1 mod 2 is 1, 2 mod 2 is 0, and 3 mod 2 is 1
• abs - absolute value i.e. abs(-4) is 4
• real - complex componet of the value i.e. real(4+5i) is 4
• complex - complex componet of the value i.e. complex(4+5i) is 5
• floor - largest whole number less than the value i.e. floor(5.1) is 5
• ceiling - smallest whole number greater than or equal to the value i.e. ceiling(5.1) is 6

There is also support binary operations (you may want to switch to binary numbers when using these operations):

• and - 2 and 3 is 2
• or - 2 or 3 is 3
• xor - 2 xor 3 is 1

Mini-mode

Clicking on the up and down arrow icon in the upper right corner of the program switches the application in and out of mini-mode. Mini-mode is design for users that have precious little screen real estate.

Always on top

Go to the Options menu and click on Always on top to keep the calculator window on top of every other window or returns it to its normal state. Always on top is helpful for working on a calculation while getting the data from another application. It is particularly useful when combined with Mini-mode.

Functions & Variables

Custom functions & variables can be defined with the = operator. For example, f(x)=x^2+2 or apples=5 which can then be used like this f(apples).

Hexadecimal & Binary numbers

To switch between binary, decimal and hexadecimal modes, go to the Options menu and click on Decimal. Binary numbers are followed by b, e.g. 2 = 10b. Hexadecimal numbers are preceded by 0x or follow by h, e.g. 16 = 10h = 0x10.

Graphing

To graph a function you must enter it into the input box

1. Click on the input box
2. Type y=x
3. Press Enter
4. Click on details
5. This will open a graph window where you can see the value of the graph, zoom in, change the graph range, and alter the function

Graphs can be either cartesian or polar, which is selected in the Graph mode dropdown in the details graph window.

Note: There are four special graph functions, y=x, x=y, r=theta, theta=r. These graph functions implicitily define the correct graph mode. For example, r=theta will graph the function in polar r over theta mode. Of course, in the graph window you can override the graph mode.
