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>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>
