Oh please, that's no argument.

Yes, I wrote that in the beginning of this thread. In the meantime, I've written a little more, but there's no need to repeat it here.

Yep, I've said my piece anyway. I won't continue the thread after this post.

BTW, you need a command that evaluates 1-800-[(10x)(13i)^2]-[sin(xy)/2.362x].

Code: Select all

Debug Sqr(9) ; Why should Sqr() exist when Pow() can do the job?Debug Pow(9,0.5)

Sqr() is there for our convenience and readability

No ^^, Sqr() uses the special ASM-Code: FSQRT which is 10 times faster than the function Pow()
So it makes your code faster.

IsOdd() and IsEven() are parts of this list:
IsPositive(), IsNegative(), IsNull(), IsPrime(), IsFibonacci(), IsPowerOfTwo(), ...

And likewise, Fred's ASM versions of IsOdd() IsEven() would be way faster than any macro we could write.

Surely, you only need either IsOdd() - or - IsEven() since IsOdd(11)=true whereas IsOdd(10)=false
- if its neded at all of course

The Sign() command does these.

....now that's a good idea.

Tenaja: Great idea!
