Thread: Not getting the actual output while displaying hex numbers in decimal format

I need to display 0-15 hex numbers[0X00-0x0F] in decimal value...& I'm getting the output but it's not exactly what it should be,below is my code..
[This not the complete code,but main part where the changes are done]

Actual output i should get is for 1v it should generate 0001,for 2v it should generate 0010 and simultenously till [15v-1111]...
But what i'm getting is exactly different to this for eg for 7v,8v&9v the bits generated are 1101,1011,1011 respectively...
Please anyone help me in resolving this.. http://img.codecall.net/public/style...001_unsure.gif
