Title: Datatype Float To Int/short Not Working?!
Post by: Mios∞ft on May 09, 2008, 04:31:00 PM

CODE

debugPrint("%g,%g\n",(((((float)(g_DefaultPad.sLThumbX+32767)/32767.0f)*100.0f)-100.0f)/100.0f)*255.0f,(((((float)(g_DefaultPad.sLThumbY+32767)/32767.0f)*100.0f)-100.0f)/100.0f)*255.0f);

Works,

However A VERY simple thing such as this show only extreme values   :

CODE

debugPrint("%d,%d\n",(int)(((((float)(g_DefaultPad.sLThumbX+32767)/32767.0f)*100.0f)-100.0f)/100.0f)*255.0f,(int)(((((float)(g_DefaultPad.sLThumbY+32767)/32767.0f)*100.0f)-100.0f)/100.0f)*255.0f);

Something wrong with FPU unit?

CODE

sprintf("%.0f,%.0f",valx,valy);

Hi,

(int) is not really converting the floats. It is just telling the compiler to interpret them as integers.
Since integers and floating point numbers are stored on a totally different way, it is normal you get a strange result.
Casting is more a way to override the parameter check of a function, so it should be used carefully.

regards.
