I remember coding actionscript in Flash and using modulo (%) to determine if a number was even or odd. It returns the remainder of the number divided by 2 and if it equals anything other than 0 then the number is odd.
Yeah. The joke is that this is the obvious solution always used in practise, but the programmer is that bad that they don’t know it and use some ridiculous alternative solutions instead.
Then you should return false, unless the remainder is also greater than or equal to the twenty second root of 4194304. Note, that I’ve only checked up to 4194304 to make sure this works, so if you need bigger numbers, you’ll have to validate on your own.
Just divide the number into its prime factors and then check if one of them is 2.

I believe that’s the proper way to do it.
or divide the number by two and if the remainder is greater than
-(4^34)but less than
70 - (((23*3*4)/2)/2)then
trueWhat if the remainder is greater than the first, but not less than the latter?
Like, for example, 1?

i hate to bring this up, but we also need a separate function for negative numbers
