Calculator Tutorial: the fundamentals
At the “> ” prompt, type a mathematical expression or formula and press enter to calculate the result. for instance, once the prompt, sort “4+5*4” followed by the enter key. The result would be:
ans = 24
If you then typewritten, “ans / 2“, your result would be:
ans = 12
To perform a fast calculation on the previous result, rather than typewriting “ans“, you'll sort the operator (*, /, +, or -) at the new prompt and also the “ans” are going to be inserted mechanically. for instance, sort “+” at the start of a replacement line, and “ans+” can mechanically seem. The “-” secret's Associate in Nursing exception. the primary “-” are going to be taken as a negative sign. sort the “-” key doubly at the start of the prompt line to get replaced with “ans-“.
Put multiple calculations during a single line, separated by a punctuation. “m = 5; m+2” would result with:
ans = 7
Using a punctuation additionally suppressed the result from being displayed, like Matlab. this can be helpful once creating script files.
Use hex and binary: “0xFF + 0b1001” would result with:
ans = 264
Use as a unit converter: “10 in->cm” converts ten inches into centimeters. The result's what percentage centimeters ar in ten inches:
ans = 25.4

Convenient options
History: Recall Previous Entries
You may press the up or down arrows to quickly copy previous entries to the present prompt, like a UNIX console.
Create Variables
For example, “m = 25” creates a variable m which might be utilized in later calculations. The variable pi = three.14159… is predefined. The variable ans is often capable the previous result.
Define Custom Functions
For example, “par(x,y) = x*y/(x+y)” creates a operate that takes a pair of parameters, x and y. Then use the operate like this: “par(10,10)“ and also the result's “5″. Functions that you simply produce ar saved to be used in future console calculator sessions. The ”list” command can show all user-defined functions.
Copy Previous Result
If you copy with no text hand-picked, the previous result's mechanically placed into the writing board and prepared to stick into another application. (Only the numerical answer is derived, the “ans =″ text is not!)
High exactitude Floating purpose
Arithmetic with high exactitude floating purpose numbers. Over a hundred important digits of decimal accuracy. Most calculators perform double-byte floating purpose calculations, that ar sixty four bit structures. Console Calculator offers you not 64 bits or 128 bits however (352 bits of arithmetic accuracy! this can be nearly astronomical exactitude.
SI-Unit Prefixes
You may use metric prefixes appended to the top of a number to mechanically modify units. for instance, “5M + 100k” + enter would result with:
ans = 5100000

Save and Open Scripts
You may save the contents of the present console to a script file which can be run once more at a later time. every line of a script file should be a sound mathematical expression and commands could also be seperated by semicolons. Script lines ending with a punctuation can have their console output suppressed once run. Lines starting with # sign ar unnoticed as comments.
Mac OS X Note: A script file is simply a noticeable computer file, but the *.script extension is appointed to Console Calculator.
Command-Line Interface (Windows Only)
The calculator has some command-line choices that will be helpful. Blind students have found it helpful, et al have found it helpful for machine-controlled calculations.
ccalc [inputfile] [-o outputfile] [-q]
• inputfile: a script file that is run now once ccalc starts.
• outputfile: the contents of the session ar saved to the current file once the CCalc window is closed.
• -q: if the -q tag is employed, the calculator can perform the calculations within the inputfile, save ends up in the outputfile, and now quit. The console calculator window ne'er even opens during this case. this can be most helpful for machine-controlled calculations.
Built-in science Functions
Built-in functions embody scientific, trig and science.h compatible functions. operate names ar case-insensitive.
• sqrt – root
• ln – natural log
• log – log base ten
• logxx – log base xx (log2 for log base a pair of, log8 for log base eight, etc)
• ln – natural log
• exp – exponential, e^…
• sin – trigonometric function
• cos – trigonometric function
• tan – tangent

|
Displayed Base |
The base can be set to either Binary, Decimal, or
Hexadecimal. 100 may be displayed as 100, 0×64, or 0b1100100. This
effects only the displayed result.
|
Display Scientific Notation |
Auto: Scientific notation is only used
for very small or large floating point numbers.Never: Scientific
notation is never used.Always Scientific: Scientific
notation is used at all times. (Scientific notation example: 123.88 is displayed as 1.23880e2)Engineering:
Engineering notation is used. (Numbers are displayed with exponents
in multiples of 3.)Engineering Prefix: Engineering SI-unit
prefixes are used. (123.88e-6 is displayed as 123.88u)Financial: Constant number of
decimal places. Scientific notation is never used.
|
Max Significant Figures |
Maximum number of significant figures to display, used
when displaying in scientific notation. (Significant figures are not applied
to integers unless they are being displayed in scientific notation.)
|
Display Thousands Separator |
For certain large numbers, when not using scientific
notation, it is helpful to use a thousands separator, such as a comma. For
example: 12,888.12. Note that this is for display
only; separators are not recognized when entering an equation.
|
Two’s Complement |
When displaying HEX or BINARY values, negative values can
optionally be displayed as two’s complement
notation.
|
Transparency |
Transparency of the window may be adjusted between 0% and
100%.
|
Command History Size |
Number of stored previous entries.
|
Always on Top |
When enabled, the window will float above all other
windows. Indicated also by a pushpin icon in the calculator window.
|
Snap-to Screen Edge |
When enabled, the window will snap to screen edged when
moved.
|
Minimize to system tray |
When enabled, the calculator will minimize to a system
tray icon.
|
Allow multiple instances |
When enabled, multiple CCalc.exe windows (instances) can
be running at the same time. Otherwise, only a single CCalc window can be
active, and this window will be brought to the forefront if CCalc.exe is
opened again.
|
Reassign Calculator AppKey |
Certain keyboards have a calculator appkey, which opens
the windows calculator by default. If this box is checked, Console Calculator
will become the default application when the appkey is pressed. (This is
accomplished by editing the Windows registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Windows\CurrentVersion\Explorer\AppKey\18 ) |
Auto-evaluate |
When enabled, current expression is calculated as it is
typed in the Status Bar. Enable the Status Bar in the Options menu or Ctrl-B.
|
European style delimiters |
When enabled, this essentially swaps the meaning of the
comma “,” and period “.” from the US custom, so that a period
separates thousands and comma indicates decimals. For example, with
european style 1,024.56 would be 1.024,56. This will also effect the character used to
separate arguments in a function. instead of f(x,y)
you must use f(x.y) to separate the x and y
arguments.
|
10-Key Calculator Mode |
When enabled, the calculator behaves as a 10-key
calculator. Basically, a tenkey assumes that you are adding a series of
numbers. Consequently, the fundamental operation consists of entering numbers
and their signs, which the application will sum:
1) Enter number.2) Enter its sign. 3) Repeat steps 1 and 2 as desired. Examples: 2+ 3+ => 5 2- 3+ => 1 2+ 3+ 4- => 1 A tenkey also keeps the last number you entered in its cache; if you enter another operator without explicitly typing a new number, the tenkey will use the contents of the cache. Examples: 2+++ => 2+ 2+ 2+ => 6 2+3++ => 2+ 3+ 3+ => 8 |

Using Decimal, Hex and Binary
Decimal numbers ar assumed, however you'll specify variety as binary with a “0b” or hex with a “0x“.
The number fifteen (decimal) in several bases:
Decimal: fifteen
Binary: 0b1111
Hexadecimal: 0xF
For example, “15 + 0×5 + 0b101” would result with:
ans = 25
Two’s Complement
When viewing negative numbers as binary or hex, two’s complement notation is nonmandatory. Two’s complement is that the manner that computers generally store signed integers in memory. for instance, -5 may well be displayed in hex as a 32-bit two’s complement, which might be 0xFFFFFFFB instead of -0×0005. this may be a handy possibility for package developers, tho' it's off by default.
Unit device
CCalc is additionally a completely featured units conversion utility. Convert from SI units to non-SI units. Convert between units of length, area, volume, force, and plenty of alternative varieties of units during a convenient manner. merely enter the amount and unit you're changing from, sort the convert operator (a minus and greater-than sign, “->”), and eventually the unit to convert to. If you wish a unit that's not a inherent, you'll outline your own custom units! Once created, new unit definitions ar saved for good within the ccalc_functions.txt for future console calculator sessions. Below ar some unit conversion examples.
