Decimal to hexadecimal conversion

Question

I have code as below:

x = readsomevalue();

print x

The printed value is an integer. I want this in hex but,

The integer which is returned(x) is having leading 0 in it(ex. 0543676). for this the standard method fails

x.to_s(16) = 0

how to solve this? since some of you have marked it as duplicate let me tell you, that the standard call fails when we have leading 0 in it, so is there anything to eliminate leading 0.
