ispow2(n) -> Bool

Test whether n is a power of two


  1. Check if a number is a power of two:

    julia> ispow2(8)

    This example checks if the number 8 is a power of two, which returns true.

  2. Verify if a number is not a power of two:

    julia> ispow2(7)

    It checks if the number 7 is a power of two, and since it is not, the function returns false.

  3. Handle negative numbers:

    julia> ispow2(-16)

    The function correctly handles negative numbers and returns false for -16, which is not a power of two.

Common mistake example:

julia> ispow2(0)

In this example, the input number is 0. However, 0 is not considered a power of two, so the function should return false instead of true. It's important to handle this edge case correctly when using ispow2.
