now it looks good on MS Vista and when a user changes size of some
widgets such as a border, font size, etc.
added: spanish language to the setup (installer)
added: the setup will remove mingwm10.dll if it exists in the program directory
added: on display tab: we can select 'deg' 'rad' or 'grad' for calculating
in such functions: sin,cos,tan,cot,asin,acos,atan,acot
added: macro TTCALC_CONVERT if not defined there will not be a convert tab
(the convert tab is not finished)
added: a new icon with following dimensions: '48x48' '32x32' '16x16'
removed: parameter for gcc: -mthreads
with -mthreads it is possible (on windows) to release some kind of
'destructors' belonging to a thread when the specific thread exists
(it prevents some kind of memory leaks)
in the TTCalc when the second thread exists then there is the end
of the program and we can not use '-mthreads'
removed: file TODO (I didn't use the file)
git-svn-id: svn://ttmath.org/publicrep/ttcalc/trunk@114 e52654a7-88a9-db11-a3e9-0013d4bc506e

<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 ';'.

|
|
|
<dt>x < y</dt>
|
|
<dd>This operator returns one if x is lower than y else it returns zero. For example:<br>
|
|
4 < 10 = 1<br>
|
|
6 < 2 = 0</dd>
|
|
|
|
<dt>x > y</dt>
|
|
<dd>This operator returns one if x is greater than y else it returns zero. For example:<br>
|
|
5 > 2 = 1<br>
|
|
5 > 8 = 0</dd>
|
|
|
|
<dt>x <= y</dt>
|
|
<dd>This operator returns one if x is lower than or equal to y else it returns zero. For example:<br>
|
|
4 <= 4 = 1<br>
|
|
7 <= 2 = 0</dd>
|
|
|
|
<dt>x >= y</dt>
|
|
<dd>This operator returns one if x is greater than or equal to y else it returns zero. For example:<br>
|
|
5 >= 5 = 1<br>
|
|
3 >= 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 && 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 && 10 = 1<br>
|
|
6 && 0 = 0<br>
|
|
0 && 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' (&&)</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>
