minus-squareRandomVideos@programming.devhexbear1·1 year agoThis code is terrible. If you input 10.66 it returns "number is odd It should be: if number % 2 == 0 return "number is even" (is_num_even = 1 or true) else return "number is not even" (is_num_even = 0 or false) linkfedilink
modulo
pseudocode:
if number % 2 == 0 return "number is even" (is_num_even = 1 or true) else return "number is odd" (is_num_even = 0 or false)plus you'd want an input validation beforehand
who needs modulo when you can get less characters out of
while (number > 1) { number -= 2; } return number;very efficient
edit: or theres the trusty iseven api
here is somewhat less:
return (number % 2) == 0;just check the last bit jesus christ, what is it with these expensive modulo operations?!
return !(n&1);are the negative numbers all even?
🤦
are u a wizard?
