Hello,

can anybody tell me why many OpenGL programmer user "1.0f" instead ofjust "1"?

for example glVertex3f(1.0f, 1.5f, 0.0f); instead of glVertex3f(1, 1.5, 0);

Is there any performance advantage or something? The compiler shouldrecognize that the function needs 3 floats or not?

Or is it just some strange coding style?

Thanks in advance.
   Christoph
