minus-squareMac@programming.devlinkfedilinkarrow-up19·edit-21 year agowho 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
minus-squareNullPointer@programming.devlinkfedilinkarrow-up8·1 year agohere is somewhat less: return (number % 2) == 0;
minus-squareMuchPineapples@lemmy.worldlinkfedilinkarrow-up8·edit-21 year agoThis is the way. Modulo takes too long to compute, bitwise compare should be a lot faster. return !(number & 0x1);

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;return !(number & 1);This is the way. Modulo takes too long to compute, bitwise compare should be a lot faster.
return !(number & 0x1);oh shit yo
