ispow2
ispow2(n) > Bool
Test whether n
is a power of two
Examples

Check if a number is a power of two:
julia> ispow2(8) true
This example checks if the number 8 is a power of two, which returns
true
. 
Verify if a number is not a power of two:
julia> ispow2(7) false
It checks if the number 7 is a power of two, and since it is not, the function returns
false
. 
Handle negative numbers:
julia> ispow2(16) false
The function correctly handles negative numbers and returns
false
for 16, which is not a power of two.
Common mistake example:
julia> ispow2(0)
true
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
.
