Basically I was saying there are too many different multiple ways of checking for something like $isodd.
If cutting the number in half includes a . in it.
If the last digit is isin 13579.
Etc.
So if Khaled made a built-in $isodd identifier, wouldn't there be more than 1 algorithm?
I guess the question is, which method is the fastest.
If you combined them, then I think a built-in 1 would be slower than a simpler if statement/custom identifier.
So I think the only way you can know if a simpler custom identifier is faster than a built-in 1 is to see the code of the built-in, and if the built-in is, twice as long as a custom 1 you can make, *shrug.* Only Khaled can bench compare the 2.
