Dynamic values for qSin and qCos giving error

[sreejithsjt]

Hi,

I was trying to draw a circle, and I need two lines inside the circle starting from the origin.
The code I used is :

QPainter Painter(this);
Painter.setRenderHint(QPainter::Antialiasing,true) ;
 
Painter.setPen(QPen(QColor(Qt::black)));
Painter.drawEllipse((circleX-(circleRadius)),(circleY-(circleRadius)),circleRadius*2,circleRadius*2); // Drawing the ellipse (giving same value for height and with)
 
Painter.setPen(QPen(QColor(Qt::black)));
Painter.drawLine(circleX,circleY,circleX+circleRadius,circleY); // Drawing the first line, starting from origin to its right side.
Painter.drawLine(circleX,circleY,circleX+(circleRadius*(qCos(angle*3.14/180.0))),circleY-(circleRadius*(qSin(angle*3.14/180.0)))); // Drawing second line. Starting from origin, the angle value with respect to first line is "angle"

QPainter Painter(this);
Painter.setRenderHint(QPainter::Antialiasing,true) ;

Painter.setPen(QPen(QColor(Qt::black)));
Painter.drawEllipse((circleX-(circleRadius)),(circleY-(circleRadius)),circleRadius*2,circleRadius*2); // Drawing the ellipse (giving same value for height and with)

Painter.setPen(QPen(QColor(Qt::black)));
Painter.drawLine(circleX,circleY,circleX+circleRadius,circleY); // Drawing the first line, starting from origin to its right side.
Painter.drawLine(circleX,circleY,circleX+(circleRadius*(qCos(angle*3.14/180.0))),circleY-(circleRadius*(qSin(angle*3.14/180.0)))); // Drawing second line. Starting from origin, the angle value with respect to first line is "angle"

The output i need to get as shown in figure.
But while drawing second line I'm getting a run time error...

Alignment trap: not handling instruction ed840a00 at [<764c58cc>]
Unhandled fault: alignment exception (0x801) at 0x3fc8f5c3

If I gave angle value as static, its working fine.

Eg:
Painter.drawLine(circleX,circleY,circleX+(circleRa dius*(qCos(60*3.14/180.0))),circleY-(circleRadius*(qSin(60*3.14/180.0))));

Can anyone tell me what I'm doing wrong and how to overcome this??
Thanks in advance.
