Double modulus operator

I know exactly how does a single modulus work. Does double modulus work the same? And assuming we have this pseudocode

j<-0
n<-10
for(j in 1:n)
{ if(!j%%2) 
    {
      next
     }
   print(j)
}

What does the 'if' condition mean and what is the output of this code?

My solution is: If J is not divisible by 2 increase J, Otherwise, print J. And the overall code outputs even numbers from (1-10). Is this solution correct?

Solution

  • The %% operators is, as far as I know, not "standard" enough to be able to use it unambiguously in pseudocode without accompanying explanation of what it is supposed to be.

    This snippet appears to be R code though, and in R the %% operator does mean remainder (with the sign of the divisor).

    But since there is a ! (logical-not) too, the code will be printing odd numbers, since it's skipping the even numbers.
