Is there an 'easy' way to get this cheap from integer ops eg to check for carry on addition of two uint8s I need to do something like
https://play.golang.org/p/IFuQcUgJlR (best I can think of) I really wanted something like var a,b uint8 = 200,100 x,error : = a+b gives x=44, with error.carry = true and error.overflow=true .. this suggestion wouldn't fit with multiple value assignments eg a,b = a+b,a-b my current method is very cludgy, and I doubt (?) it compiles to anything like the minimal assembler equivalent. Thinking about a builtin math error variable (different from the Error package) - functioning as struct{overflow,carry,negative,underflow etc bool} This isn't going to happen or be fixed soon.. Is there an easier way, in terms of both efficiency (ie what it compiles to) and appearance (ie "do what I say" quality), .. or any other thoughts ?? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
