This is a general principle: the point of scripts is verifying provided information, not computing it. As another example, this means that there is no need for a division or square root opcode if one has a multiplication opcode. -- Pieter -- You received this message because you are subscribed to the Google Groups "Bitcoin Development Mailing List" group.
