how to take off leading zero

I have fields like '0006','0007','0004'
etc. I need to convert this in 4 char field as right justify 6,7,4. How would I do that?

Another question:

fields in input file as 77,77.0,77.90,77.99,

I need to show them right justify in 10 chars field as 77.00,77.00,77.90 and 77.99
How would I do that?

Please help!!!!!!!!!

Thanks in advance!!

How about

select str(convert(int,'0004'),4,0)

select str(77,10,2), str(77.79,10,2)
