You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: burn.go
    path of file: ./repos/lotus/chain/vm
    
    the code of the file until where you have to start completion: package vm

	if gasUsed == 0 {
		return 0, gasLimit
	}

	// over = gasLimit/gasUsed - 1 - 0.1
	// over = min(over, 1)
	// gasToBurn = (gasLimit - gasUsed) * over

	// so to factor out division from `over`
	// over*gasUsed = min(gasLimit - (11*gasUsed)/10, gasUsed)
	// gasToBurn = ((gasLimit - gasUsed)*over*gasUsed) / gasUsed
	over := gasLimit - (gasOveruseNum*gasUsed)/gasOveruseDenom
	if over < 0 {
		return gasLimit - gasUsed, 0
	}

	// if we want sharper scaling it goes here:
	// over *= 2

	if over > gasUsed {
		over = gasUsed
	}

	// needs bigint, as it overflows in pathological case gasLimit > 2^32 gasUsed = gasLimit / 2
	gasToBurn := big.NewInt(gasLimit - gasUsed)
	gasToBurn = big.Mul(gasToBurn, big.NewInt(over))
