# Examples of errors detected by the V3041 diagnostic

V3041. The expression was implicitly cast from integer type to real type. Consider utilizing an explicit type cast to avoid the loss of a fractional part.

## Sony ATF

V3041 The expression was implicitly cast from 'int' type to 'float' type. Consider utilizing an explicit type cast to avoid the loss of a fractional part. An example: double A = (double)(X) / Y;. Atf.Gui.OpenGL.vs2010 ArcBallCameraController.cs 216

``````
private Vec3F ProjectToArcball(Point point)
{
float x = (float)point.X / (m_width / 2);   // <=

float y = (float)point.Y / (m_height / 2);  // <=

x = x - 1;
y = 1 - y;
if (x < -1)
x = -1;
else if (x > 1)
x = 1;
if (y < -1)
y = -1;
else if (y > 1)
y = 1;
