(It is often used in other calculations, however, so perhaps one opcode would be better than 3.) sqrt has traditionally been provided in languages, although it (and all other roots) could simply be an power (inverse x). atan2 is also often traditionally provided in a language, since it identifies the proper quadrant. Others would include abs, floor, ceil, round, mod - don't know if those are basic or "fancy" to you. I suspect you may have those already.... The question arises what do you do as its opcode, and what languages features can be a series of opcodes. -- Bryan C. Warnock bwarnock@gtemail.netThread Previous | Thread Next
