Re: modulus question

[vinoth.ree]

To check if a number $day is divisible by divisor(3), use the modulus operator, %:

If the number divisible by 3 then the modulus will return remainder 0, so the if condition will fail so add your logic in else condition.

if ($day % 3) { 
  # does not divide cleanly 
} 
else {
 # does. 
}

(OR)

Even you can use the same as your if(($day%3) == 0) condition of checking the reminder is equal to 0. In this case you can add your logic in if(..) itself

vinoth in a case like this by not providing any code there is a chance that the OP will show us what he has tried and thus allow us to provide much better help than we can by just giving a dollop of code.

Very often the errors beginners make fall into common patterns and tell you a lot about how they are thinking and where the root of their problem really lie. By just giving a solution, even if we take time to explain how the solution works, beginners will run off happy, but none the wiser.

Hi GrandFather,

Yes I agree with you, I regret for that. As per my understanding I though he just confused if(....) condition with modulus(%) operator. That's why I just given him the explanation.
