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.
