numbersToAscending()

bool numbersToAscending	(	const TCEString &	lhs,
		const TCEString &	rhs
	)

Custom comparator that orders operation names correctly number-wise.

For instance, in an std::set operation names are ordered followingly: ADD32X16, ADD32X4, ADD32X8, XOR1024, XOR512, XOR64

This function corrects the operation name order to be the following: ADD32X4, ADD32X8, ADD32X16, XOR64, XOR512, XOR1024
