Checking if a number is power of two in Julia – ispow2() Method
The ispow2()
is an inbuilt function in julia which is used to test whether the specified number n is a power of two or not.
Syntax: ispow2(n::Integer)
Parameters:
- n::Integer: Specified number.
Returns: It returns true if the given number is power of 2 else false.
Example 1:
# Julia program to illustrate # the use of ispow2() method # Getting true if the given number # is power of 2 else false. println(ispow2( 1 )) println(ispow2( 2 )) println(ispow2( 4 )) println(ispow2( 8 )) |
Output:
true true true true
Example 2:
# Julia program to illustrate # the use of ispow2() method # Getting true if the given number # is power of 2 else false. println(ispow2( 3 )) println(ispow2( 5 )) println(ispow2( 7 )) println(ispow2( 9 )) |
Output:
false false false false
