Solving expressions

[Farabi]

Also, 2^1.5 mean (2*1)*(2*0.5) in case you did not know.

4^4.5 = (4^4)*(4*0.5)

If M$ Calculator says 0^0=1 who am I to disagree ^ ^ :lol

[dedndave]

oh - and....
0/0 and 1/0 are not 0   :bg
they are both undefined
although, i've had calculus instructors try to tell me they were infinity - lol

TmX,
    «I found a simple bug»

    Its not a bug: The exponent must be a positive constant from 0 to 31
                   NOT an expression

dedndave,
          My Calcula19 gives 0^0=0 ( in higher math it is undefined )
          but (expression)^0 = 1   if expression is not 0
         
oex,
          «If M$ Calculator says 0^0=1 who am I to disagree»

          I disagree, if the base tends to 0 first it is 0 not 1
          Calcula19 must give a result and gives 0
         
Farabi,
          «Also, 2^1.5 mean (2*1)*(2*0.5) in case you did not know»

          My Calcula19 gives ERROR because exponent must be from 0 to 31

          Calcula19 works with any integer from -4 294 967 295 to 4 294 967 295
          so the result must be any integer from -4 294 967 295 to 4 294 967 295
          but the exponent must be from 0 to 31
           
        Thanks all

dedndave,
          My Calcula19 gives 0^0=0 ( in higher math it is undefined )

i have taken too many courses in "higher math" - lol
what i am saying is, this is still a subject of discussion and disagreement amongst "higher" mathematicians

a realistic approach is to apply the right rule for the job, after evaluating with 0, 1, and undefined
usually, if this result pops out it means.....

Well I guess it is better than giving a crash "Division by zero" error message.

Download the latest patch, it fixed, look



:green

 :lol

you guys can do math, too !!!

[oex]

The assumption that has to be made is not whether 0^0=0 or 0^0=1 (as both are wrong).... The question is, with the avoidance of an error which will produce the best result in a greater equation....

If 0 then further
% = Divide By Zero Error
/ = Divide By Zero Error
* = 0
+ = Right Answer
- = Right Answer

If 1 then further
% = Right Answer
/ = Right Answer
* = Right Answer
+ = Answer + 1
- = Answer - 1

Either way a further answer is wrong :lol the difference is whether your answer is a maximum of 1 out or result out/errors I think :lol

0^0=1 is Error Handling (As it handles crash errors at the risk of minimal data loss)
0^0=0 is lazy Error Handling (As it favours one crash error over the next crash error)

        Yes i do

        EDIT:
                another solution is: 0^0= ERROR
                If you prefer edit .asm change it to exit with ERROR

:lol Yep.... Contextualising is the best policy....

0/0=?
?*0=0
(0 = -Infinity - 0 - +Infinity

0/0*1=0
0/0*2=0
(1=2)

X^0=1
(Why except 0?)

So much for logic :lol

oex,
        contextualizing ? what do you mean ?

Deriving a result based on result you need ie if your program will crash if you supply 0 or return error and it will sink the ship like here then return 1 even though it's wrong :lol

                 too much logic... under logic  :wink

X^0=1                   0^X=0
(Why except 0?)         (Why except 0?)

anyone tried this

Code Select Expand


mov eax,some_value
xor ecx,ecx
div ecx


I dunno if Im making mistake, but it create a fault on the processor. Anyone experiencing that? I did.
