added: a user can change the names of variables or functions now

Browse Source 
changed: the program uses TTMath 0.8.0 now
added: functions: from TTMath 0.8.0:        
       DegToDeg(deg, min, sec), DegToRad(deg), DegToRad(deg, min, sec),
       RadToDeg(rad), Ceil(x), Floor(x), Sqrt(x), Sinh(x), Cosh(x),
       Tanh(x) /Tgh(x)/, Coth(x) /Ctgh(x)/
added: a help
changed: from TTMath 0.8.0:
       renamed: CTan()  into Cot()  or Ctg()
       renamed: ACTan() into ACot() or ACtg()
       Factorial() has a history log now (it can remember last
       10 calculated values)
added: a directory 'help' with files of the help
added: a directory 'setup' with files needed to make an installer
       (we're using InnoSetup Compiler to make it)
fixed: the vertical size of the main window when a user uses a different size
       of the window caption (especially under the Windows XP Luna)
fixed: on Windows 9x: the program hung when a user clicks on a control 
       on the first tab (the procedure SetNextFocus(...) has been completely
       rewritten and the flag WS_EX_CONTROLPARENT on the tab dialogs has
       gone away)
fixed: when started navigating from the keyboard the program showed a wrong
       variable or a funtion in the edit dialog

<h1>TTCalc</h1>
<p>
TTCalc is a mathematical calculator. It has a nice user interface, formulas for
calculating can be inserted by using a keyboard or a mouse. The result is automatically
shown in a second window without using any additional keys such as 'equal'. The
program possess trigonometric functions, inverse trigonometric functions, hyperbolic
functions, logical operators, logarithms, functions for converting between degrees and
radians and so on. Additionally the program allows the user to define his own
variables and functions. Calculations are performed by using floating point numbers
with three kind of precision, the biggest has 288 bits for its mantissa and 96 bits
for its exponent that is about 2.551...e+11925026709067095507636213441 with 85 valid
decimal digits. The program independently allows to insert and display values with
the base (radix) from two to sixteen.

<h1>Comparative and logical operators and functions</h1>
<p>
We assume that the logical false is represented by zero and the logical true is represented by the
value different from zero. <strong>Note:</strong> If a function takes more than one argument, the arguments are separated with semicolon ';'.
</p>
<dl>
<dt>x &lt; y</dt>
<dd>This operator returns one if x is lower than y else it returns zero. For example:<br>
4 &lt; 10 = 1<br>
6 &lt; 2 = 0</dd>
<dt>x &gt; y</dt>
<dd>This operator returns one if x is greater than y else it returns zero. For example:<br>
5 &gt; 2 = 1<br>
5 &gt; 8 = 0</dd>
<dt>x &lt;= y</dt>
<dd>This operator returns one if x is lower than or equal to y else it returns zero. For example:<br>
4 &lt;= 4 = 1<br>
7 &lt;= 2 = 0</dd>
<dt>x &gt;= y</dt>
<dd>This operator returns one if x is greater than or equal to y else it returns zero. For example:<br>
5 &gt;= 5 = 1<br>
3 &gt;= 4 = 0</dd>
<dt>x == y</dt>
<dd>This operator returns one if x is equal y else it returns zero. For example:<br>
4 == 4 = 1<br>
6 == 2 = 0</dd>
<dt>x != y</dt>
<dd>This operator returns one if x is different from y else it returns zero. For example:<br>
5 != 2 = 1<br>
5 != 5 = 0</dd>
<dt>x &amp;&amp; y (logical and)</dt>
<dd>This operator returns one if both x and y are different from zero else it returns zero. For example:<br>
4 &amp;&amp; 10 = 1<br>
6 &amp;&amp; 0 = 0<br>
0 &amp;&amp; 0 = 0</dd>
<dt>x || y (logical or)</dt>
<dd>This operator returns one either if x or y are different from zero else it returns zero. For example:<br>
5 || 2 = 1<br>
0 || 3 = 1<br>
0 || 0 = 0</dd>
<dt>if(condition; if_true; if_false)</dt>
<dd>If the 'condition' is true (different from zero) the function returns 'if_true' else it returns 'if_false', e.g.<br>
if( 0 ; 20 ; 30) = 30<br>
if( 1 ; 20 ; 30) = 20<br>
if( 4<5 ; 10 ; 50) = 10<br>
if( 6>10 ; 200 ; 100) = 100</dd>
<dt>and(x ; y)</dt>
<dd>This function does the same thing as the logical operator 'and' (&amp;&amp;)</dd>
<dt>or(x ; y)</dt>
<dd>This function does the same thing as the logical operator 'or' (||)</dd>
<dt>not(x)</dt>
<dd>If the x is true (different from zero) this function returns zero, otherwise it returns one, e.g.<br>
not(15)=0<br>
not(0)=1</dd>

<h1>Tips</h1>
<p>
If you want to clear the input edit or if you want to put something in and the focus is
somewhere on the tabs just type ESC, the entire edit will be selected and have a focus.
</p>
<p>
If you want to insert a value with a base (radix) 2 or 16 use the unary operator &amp; (for the base 2)
or # (for the base 16).
For example &amp;10=2 (decimal), #10=16 (decimal). When you're using these operators
then 'input' mode on the 'display' tab is ignored.
</p>
<p>
You can calculate more than one formula at the same time. To achive this use a semicolon
in the global space, for example type '2+4 ; 5*10' and the result will be '6&nbsp;&nbsp;&nbsp;50'.

<h1>User defined variables and functions</h1>
<p>
You are allowed to define your own variables and functions. As a name of a variable or a function
can be a name consists of letters and digits but the first character must be a letter. Names are case-insensitive
that means 'name' is the same as 'NaMe'. For example these
are correct names: a, b, c3, myname, etc. During defining variables and functions you can call another
variables and functions but you cannot call a variable or a function twice. Recurrence calling are not allowed.
</p>
<p>
Functions can get maximum 9 parameters. You have to specify how many parameters your function takes and
you can refer to them by using the variable 'x' with a number from 1 to 9 ('x' without a number means 'x1').
For example you can define a function 'xy' as 'x1*x2' (of course without apostrophes), set the 'parameters' on 2
and then put into the edit box an expression 'xy(10;20)', the result will be 200. Note that we use a semicolon
to separate arguments in a function.

<h1>Numbers</h1>
You can type numbers directly using a keyboard or insert them by a mouse. This is a simple edit window,
you can use arrow keys etc. and copy&amp;paste a text by using standard shortcuts such as CTRL+C and CTRL+V.
As the decimal point can be either a comma or a dot that means 1,234 is the same as 1.234.
