Hi all,
is there any easy why to check if a value is odd or not?
ignore every answer that doesn't use the % operator.
Thanks // Jonas
ie my answer! I think the % operator is the best way, but there was
nothing wrong with the answer I gave in that it would let you know
whether the value is odd or not. But, I guess being not as clever as the
other guys means I better go... sob sob....
But there was something wrong with it. You're using string operations on
a number to find out if it is odd. That means that it is many TIMES
slower, and if he needs to do this in a loop, using string functions is
going to be horribly slow compared to a simple modulus.
Just because code "works" doesn't mean that it is acceptable. Spending a
thousand times more computational time to solve a problem than is needed
is a recipe for disaster.
