isodd

isodd(x::Integer) -> Bool

Returns true if x is odd (that is, not divisible by 2), and false otherwise.

julia> isodd(9)
true

julia> isodd(10)
false

Examples

Check if a number is odd:

In Julia, you can use the isodd function to determine whether a given integer is odd or not. It returns true if the number is odd and false otherwise.

julia> isodd(9)
true

julia> isodd(10)
false

Here are a few common examples of using the isodd function:

1. Check if a variable is an odd number:

   julia> num = 7;
   julia> isodd(num)
   true

2. Use isodd in conditional statements:

   julia> x = 12;
   julia> if isodd(x)
             println("The number is odd.")
         else
             println("The number is even.")
         end

3. Filter odd numbers from an array:

   julia> numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
   julia> filter(isodd, numbers)
   5-element Array{Int64,1}:
   1
   3
   5
   7
   9

Remember, the isodd function is applicable only to integers (Int type) and not to other numeric types.
