# 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.
