Greater than

The gt instructions, short for greater than, check if a number is greater than another number. If the first number is greater than the second number equal 1 will be pushed on to the stack, otherwise 0 will be pushed on to the stack.

The integer types have separate greater than instructions for signed (gt_s) and unsigned (gt_u) numbers.
